How to calculate the greatest common factor and the least common multiple of 11 and 54
Because 11 is prime, 54 is composite, a prime and a composite are coprime
Common multiple: just multiply the two numbers. [11,54] = 11 × 54 = 594
Common factor: (11,54) = 1
Finding the greatest common divisor and the least common multiple of 13,39 and 91 finding the greatest common divisor and the least common multiple of 13,39 and 91
(13,39）=3 [13,39]=273
