Given numbers are 643, 957, 882, 769

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

Apply this formula for all numbers.

Step1:

LCM(643, 957) = 615351

GCD(643, 957) = ( 643 x 957 ) / 615351

= 643 / 957

= 643

Step2:

LCM(1, 882) = 882

GCD(1, 882) = ( 1 x 882 ) / 882

= 1 / 882

= 1

Step3:

LCM(1, 769) = 769

GCD(1, 769) = ( 1 x 769 ) / 769

= 1 / 769

= 1

So, Greatest Common Divisor of 643, 957, 882, 769 is 1
