Given numbers are 291, 458, 125, 639
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(291, 458) = 133278
GCD(291, 458) = ( 291 x 458 ) / 133278
= 291 / 458
= 291
Step2:
LCM(1, 125) = 125
GCD(1, 125) = ( 1 x 125 ) / 125
= 1 / 125
= 1
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 291, 458, 125, 639 is 1
