Given numbers are 407, 165, 598, 638
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(407, 165) = 6105
GCD(407, 165) = ( 407 x 165 ) / 6105
= 407 / 165
= 407
Step2:
LCM(11, 598) = 6578
GCD(11, 598) = ( 11 x 598 ) / 6578
= 11 / 598
= 11
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 407, 165, 598, 638 is 1
