Given numbers are 638, 120, 486, 411
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 120) = 38280
GCD(638, 120) = ( 638 x 120 ) / 38280
= 638 / 120
= 638
Step2:
LCM(2, 486) = 486
GCD(2, 486) = ( 2 x 486 ) / 486
= 2 / 486
= 2
Step3:
LCM(2, 411) = 822
GCD(2, 411) = ( 2 x 411 ) / 822
= 2 / 411
= 2
So, Greatest Common Divisor of 638, 120, 486, 411 is 1
