44 and 55, 10 and 9, 60 and 45, 36 and 54

44 and 55, 10 and 9, 60 and 45, 36 and 54

Least common multiple of 44 and 55 220
10 and 9, 90
60 and 45 15 × 4 × 3 = 180
36 and 54 18 × 2 × 3 = 108

18. What is the least common multiple of 54 and 108?
RT,

For three numbers, if the maximum number is a multiple of the smaller two numbers, then their least common multiple is the maximum number; for three numbers, if the smaller number is a divisor of the other two numbers, then their greatest common divisor is the minimum number. Because 108 is a multiple of 18 and 54, the least common multiple of 18, 54 and 108 is 108

The least common multiple of 27 and 54

27=3*9
54=6*9=2*27=54*1
So the least common multiple of the two is 54

One hundred minus one is not ninety-nine to one word

White: 100 (minus one)
