Choose five different numbers from the nine numbers 1-9 to form a five digit number. It is required that they can be divided by 3, 5, 7 and 11. What is the minimum speed!

Choose five different numbers from the nine numbers 1-9 to form a five digit number. It is required that they can be divided by 3, 5, 7 and 11. What is the minimum speed!

13725 the smallest five digits divisible by 3 5 7 11 (five different numbers)
So it's 13725

Choose five different arrays from the nine numbers 0 ~ 9 to form a five digit array, which is required to be divisible by 3, 7, 5 and 11. What is the maximum number?

98175
9 of 10
3,5,7,11 least common multiple = 3 * 5 * 7 * 11 = 1155
Maximum five digits 99999 / 1155 rounded = 86
1155 * 86 = 99330, the number is repeated, which does not meet the requirements
1155*85=98175

The earth's orbit around the sun is close to a circle. The radius of their orbit is 1.5 times the octave of 10. How many kilometers per second is the earth's revolution speed?
There are trees and big hands,

Revolution period T = 1, y = 365, d = 3.1536 × 10 ^ 7 S
v=2πr/T=3.0×10^4 m/s=30 km/s
Note: r = 1.5 × 10 ^ 11 m = 1.5 × 10 ^ 8 km
