Given numbers are 430, 638, 511, 587
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(430, 638) = 137170
GCD(430, 638) = ( 430 x 638 ) / 137170
= 430 / 638
= 430
Step2:
LCM(2, 511) = 1022
GCD(2, 511) = ( 2 x 511 ) / 1022
= 2 / 511
= 2
Step3:
LCM(1, 587) = 587
GCD(1, 587) = ( 1 x 587 ) / 587
= 1 / 587
= 1
So, Greatest Common Divisor of 430, 638, 511, 587 is 1
