The list of prime factors of all numbers are
Prime factors of 615 are 3 x 5 x 41
Prime factors of 666 are 2 x 3 x 3 x 37
Prime factors of 910 are 2 x 5 x 7 x 13
Prime factors of 921 are 3 x 307
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 615, 666, 910, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(615, 666) = 136530
GCD(615, 666) = ( 615 x 666 ) / 136530
= 615 / 666
= 615
Step2:
LCM(3, 910) = 2730
GCD(3, 910) = ( 3 x 910 ) / 2730
= 3 / 910
= 3
Step3:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
So, Greatest Common Divisor of 615, 666, 910, 921 is 1
