Given numbers are 642, 915, 448, 332

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 915 are 3 x 5 x 61

Prime factors of 448 are 2 x 2 x 2 x 2 x 2 x 2 x 7

Prime factors of 332 are 2 x 2 x 83

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

Given numbers are 642, 915, 448, 332

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

Apply this formula for all numbers.

Step1:

LCM(642, 915) = 195810

GCD(642, 915) = ( 642 x 915 ) / 195810

= 642 / 915

= 642

Step2:

LCM(3, 448) = 1344

GCD(3, 448) = ( 3 x 448 ) / 1344

= 3 / 448

= 3

Step3:

LCM(1, 332) = 332

GCD(1, 332) = ( 1 x 332 ) / 332

= 1 / 332

= 1

So, Greatest Common Divisor of 642, 915, 448, 332 is 1
