Prime factors of 615 are 3 x 5 x 41
Prime factors of 175 are 5 x 5 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 651, 780, 615, 175
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(651, 780) = 169260
GCD(651, 780) = ( 651 x 780 ) / 169260
= 651 / 780
= 651
Step2:
LCM(3, 615) = 615
GCD(3, 615) = ( 3 x 615 ) / 615
= 3 / 615
= 3
Step3:
LCM(3, 175) = 525
GCD(3, 175) = ( 3 x 175 ) / 525
= 3 / 175
= 3
So, Greatest Common Divisor of 651, 780, 615, 175 is 1
