Given numbers are 615, 801, 455, 942

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

Prime factors of 801 are 3 x 3 x 89

Prime factors of 455 are 5 x 7 x 13

Prime factors of 942 are 2 x 3 x 157

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

Given numbers are 615, 801, 455, 942

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

Apply this formula for all numbers.

Step1:

LCM(615, 801) = 164205

GCD(615, 801) = ( 615 x 801 ) / 164205

= 615 / 801

= 615

Step2:

LCM(3, 455) = 1365

GCD(3, 455) = ( 3 x 455 ) / 1365

= 3 / 455

= 3

Step3:

LCM(1, 942) = 942

GCD(1, 942) = ( 1 x 942 ) / 942

= 1 / 942

= 1

So, Greatest Common Divisor of 615, 801, 455, 942 is 1
