Given numbers are 422, 338, 527, 639
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(422, 338) = 71318
GCD(422, 338) = ( 422 x 338 ) / 71318
= 422 / 338
= 422
Step2:
LCM(2, 527) = 1054
GCD(2, 527) = ( 2 x 527 ) / 1054
= 2 / 527
= 2
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 422, 338, 527, 639 is 1
