Given numbers are 642, 631, 63, 519

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

Apply this formula for all numbers.

Step1:

LCM(642, 631) = 405102

GCD(642, 631) = ( 642 x 631 ) / 405102

= 642 / 631

= 642

Step2:

LCM(1, 63) = 63

GCD(1, 63) = ( 1 x 63 ) / 63

= 1 / 63

= 1

Step3:

LCM(1, 519) = 519

GCD(1, 519) = ( 1 x 519 ) / 519

= 1 / 519

= 1

So, Greatest Common Divisor of 642, 631, 63, 519 is 1
