Given numbers are 642, 841, 262, 783

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 841 are 29 x 29

Prime factors of 262 are 2 x 131

Prime factors of 783 are 3 x 3 x 3 x 29

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

Given numbers are 642, 841, 262, 783

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

Apply this formula for all numbers.

Step1:

LCM(642, 841) = 539922

GCD(642, 841) = ( 642 x 841 ) / 539922

= 642 / 841

= 642

Step2:

LCM(1, 262) = 262

GCD(1, 262) = ( 1 x 262 ) / 262

= 1 / 262

= 1

Step3:

LCM(1, 783) = 783

GCD(1, 783) = ( 1 x 783 ) / 783

= 1 / 783

= 1

So, Greatest Common Divisor of 642, 841, 262, 783 is 1
