Given numbers are 386, 642, 690, 525

The list of prime factors of all numbers are

Prime factors of 386 are 2 x 193

Prime factors of 642 are 2 x 3 x 107

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 525 are 3 x 5 x 5 x 7

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

Given numbers are 386, 642, 690, 525

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

Apply this formula for all numbers.

Step1:

LCM(386, 642) = 123906

GCD(386, 642) = ( 386 x 642 ) / 123906

= 386 / 642

= 386

Step2:

LCM(2, 690) = 690

GCD(2, 690) = ( 2 x 690 ) / 690

= 2 / 690

= 2

Step3:

LCM(2, 525) = 1050

GCD(2, 525) = ( 2 x 525 ) / 1050

= 2 / 525

= 2

So, Greatest Common Divisor of 386, 642, 690, 525 is 1
