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

Apply this formula for all numbers.

Step1:

LCM(972, 842) = 409212

GCD(972, 842) = ( 972 x 842 ) / 409212

= 972 / 842

= 972

Step2:

LCM(2, 472) = 472

GCD(2, 472) = ( 2 x 472 ) / 472

= 2 / 472

= 2

Step3:

LCM(2, 158) = 158

GCD(2, 158) = ( 2 x 158 ) / 158

= 2 / 158

= 2

So, Greatest Common Divisor of 972, 842, 472, 158 is 2
