Given numbers are 427, 137, 639, 753

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

Apply this formula for all numbers.

Step1:

LCM(427, 137) = 58499

GCD(427, 137) = ( 427 x 137 ) / 58499

= 427 / 137

= 427

Step2:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

Step3:

LCM(1, 753) = 753

GCD(1, 753) = ( 1 x 753 ) / 753

= 1 / 753

= 1

So, Greatest Common Divisor of 427, 137, 639, 753 is 1
