Given numbers are 622, 157, 154, 642

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

Apply this formula for all numbers.

Step1:

LCM(622, 157) = 97654

GCD(622, 157) = ( 622 x 157 ) / 97654

= 622 / 157

= 622

Step2:

LCM(1, 154) = 154

GCD(1, 154) = ( 1 x 154 ) / 154

= 1 / 154

= 1

Step3:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 622, 157, 154, 642 is 1
