Given numbers are 424, 248, 745, 138

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

Apply this formula for all numbers.

Step1:

LCM(424, 248) = 13144

GCD(424, 248) = ( 424 x 248 ) / 13144

= 424 / 248

= 424

Step2:

LCM(8, 745) = 5960

GCD(8, 745) = ( 8 x 745 ) / 5960

= 8 / 745

= 8

Step3:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

So, Greatest Common Divisor of 424, 248, 745, 138 is 1
