Given numbers are 725, 441, 639, 117

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

Apply this formula for all numbers.

Step1:

LCM(725, 441) = 319725

GCD(725, 441) = ( 725 x 441 ) / 319725

= 725 / 441

= 725

Step2:

LCM(1, 639) = 639

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

= 1 / 639

= 1

Step3:

LCM(1, 117) = 117

GCD(1, 117) = ( 1 x 117 ) / 117

= 1 / 117

= 1

So, Greatest Common Divisor of 725, 441, 639, 117 is 1
