Given numbers are 638, 647, 853, 532

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

Apply this formula for all numbers.

Step1:

LCM(638, 647) = 412786

GCD(638, 647) = ( 638 x 647 ) / 412786

= 638 / 647

= 638

Step2:

LCM(1, 853) = 853

GCD(1, 853) = ( 1 x 853 ) / 853

= 1 / 853

= 1

Step3:

LCM(1, 532) = 532

GCD(1, 532) = ( 1 x 532 ) / 532

= 1 / 532

= 1

So, Greatest Common Divisor of 638, 647, 853, 532 is 1
