Prime factors of 685 are 5 x 137
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 610, 253, 556, 685
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(610, 253) = 154330
GCD(610, 253) = ( 610 x 253 ) / 154330
= 610 / 253
= 610
Step2:
LCM(1, 556) = 556
GCD(1, 556) = ( 1 x 556 ) / 556
= 1 / 556
= 1
Step3:
LCM(1, 685) = 685
GCD(1, 685) = ( 1 x 685 ) / 685
= 1 / 685
= 1
So, Greatest Common Divisor of 610, 253, 556, 685 is 1
