Given numbers are 724, 208, 120, 639

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

Apply this formula for all numbers.

Step1:

LCM(724, 208) = 37648

GCD(724, 208) = ( 724 x 208 ) / 37648

= 724 / 208

= 724

Step2:

LCM(4, 120) = 120

GCD(4, 120) = ( 4 x 120 ) / 120

= 4 / 120

= 4

Step3:

LCM(4, 639) = 2556

GCD(4, 639) = ( 4 x 639 ) / 2556

= 4 / 639

= 4

So, Greatest Common Divisor of 724, 208, 120, 639 is 1
