Given numbers are 642, 761, 924, 381

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 761 are 761

Prime factors of 924 are 2 x 2 x 3 x 7 x 11

Prime factors of 381 are 3 x 127

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

Given numbers are 642, 761, 924, 381

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

Apply this formula for all numbers.

Step1:

LCM(642, 761) = 488562

GCD(642, 761) = ( 642 x 761 ) / 488562

= 642 / 761

= 642

Step2:

LCM(1, 924) = 924

GCD(1, 924) = ( 1 x 924 ) / 924

= 1 / 924

= 1

Step3:

LCM(1, 381) = 381

GCD(1, 381) = ( 1 x 381 ) / 381

= 1 / 381

= 1

So, Greatest Common Divisor of 642, 761, 924, 381 is 1
