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

Apply this formula for all numbers.

Step1:

LCM(438, 942) = 68766

GCD(438, 942) = ( 438 x 942 ) / 68766

= 438 / 942

= 438

Step2:

LCM(6, 138) = 138

GCD(6, 138) = ( 6 x 138 ) / 138

= 6 / 138

= 6

Step3:

LCM(6, 562) = 1686

GCD(6, 562) = ( 6 x 562 ) / 1686

= 6 / 562

= 6

So, Greatest Common Divisor of 438, 942, 138, 562 is 2
