Given numbers are 638, 858, 147, 943

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

Apply this formula for all numbers.

Step1:

LCM(638, 858) = 24882

GCD(638, 858) = ( 638 x 858 ) / 24882

= 638 / 858

= 638

Step2:

LCM(22, 147) = 3234

GCD(22, 147) = ( 22 x 147 ) / 3234

= 22 / 147

= 22

Step3:

LCM(1, 943) = 943

GCD(1, 943) = ( 1 x 943 ) / 943

= 1 / 943

= 1

So, Greatest Common Divisor of 638, 858, 147, 943 is 1
