Given numbers are 354, 535, 643, 615

The list of prime factors of all numbers are

Prime factors of 354 are 2 x 3 x 59

Prime factors of 535 are 5 x 107

Prime factors of 643 are 643

Prime factors of 615 are 3 x 5 x 41

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 354, 535, 643, 615

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

Apply this formula for all numbers.

Step1:

LCM(354, 535) = 189390

GCD(354, 535) = ( 354 x 535 ) / 189390

= 354 / 535

= 354

Step2:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

Step3:

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

= 1 / 615

= 1

So, Greatest Common Divisor of 354, 535, 643, 615 is 1
