Given numbers are 638, 608, 235, 978
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 608) = 193952
GCD(638, 608) = ( 638 x 608 ) / 193952
= 638 / 608
= 638
Step2:
LCM(2, 235) = 470
GCD(2, 235) = ( 2 x 235 ) / 470
= 2 / 235
= 2
Step3:
LCM(1, 978) = 978
GCD(1, 978) = ( 1 x 978 ) / 978
= 1 / 978
= 1
So, Greatest Common Divisor of 638, 608, 235, 978 is 1
