Given numbers are 643, 767, 561, 635

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

Apply this formula for all numbers.

Step1:

LCM(643, 767) = 493181

GCD(643, 767) = ( 643 x 767 ) / 493181

= 643 / 767

= 643

Step2:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

Step3:

LCM(1, 635) = 635

GCD(1, 635) = ( 1 x 635 ) / 635

= 1 / 635

= 1

So, Greatest Common Divisor of 643, 767, 561, 635 is 1
