GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(639, 916) = 585324

GCD(639, 916) = ( 639 x 916 ) / 585324

= 639 / 916

= 639

Step2:

LCM(1, 888) = 888

GCD(1, 888) = ( 1 x 888 ) / 888

= 1 / 888

= 1

Step3:

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

= 1 / 378

= 1

So, Greatest Common Divisor of 639, 916, 888, 378 is 1
