Given numbers are 231, 245, 422, 957
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(231, 245) = 8085
GCD(231, 245) = ( 231 x 245 ) / 8085
= 231 / 245
= 231
Step2:
LCM(7, 422) = 2954
GCD(7, 422) = ( 7 x 422 ) / 2954
= 7 / 422
= 7
Step3:
LCM(1, 957) = 957
GCD(1, 957) = ( 1 x 957 ) / 957
= 1 / 957
= 1
So, Greatest Common Divisor of 231, 245, 422, 957 is 1
