Given numbers are 240, 432, 877, 638
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(240, 432) = 2160
GCD(240, 432) = ( 240 x 432 ) / 2160
= 240 / 432
= 240
Step2:
LCM(48, 877) = 42096
GCD(48, 877) = ( 48 x 877 ) / 42096
= 48 / 877
= 48
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 240, 432, 877, 638 is 1
