Prime factors of 860 are 2 x 2 x 5 x 43
Prime factors of 615 are 3 x 5 x 41
Prime factors of 352 are 2 x 2 x 2 x 2 x 2 x 11
Prime factors of 257 are 257
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 860, 615, 352, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(860, 615) = 105780
GCD(860, 615) = ( 860 x 615 ) / 105780
= 860 / 615
= 860
Step2:
LCM(5, 352) = 1760
GCD(5, 352) = ( 5 x 352 ) / 1760
= 5 / 352
= 5
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 860, 615, 352, 257 is 1
