Given numbers are 643, 615, 159, 633

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

Apply this formula for all numbers.

Step1:

LCM(643, 615) = 395445

GCD(643, 615) = ( 643 x 615 ) / 395445

= 643 / 615

= 643

Step2:

LCM(1, 159) = 159

GCD(1, 159) = ( 1 x 159 ) / 159

= 1 / 159

= 1

Step3:

LCM(1, 633) = 633

GCD(1, 633) = ( 1 x 633 ) / 633

= 1 / 633

= 1

So, Greatest Common Divisor of 643, 615, 159, 633 is 1
