Given numbers are 156, 225, 387, 761

The list of prime factors of all numbers are

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 225 are 3 x 3 x 5 x 5

Prime factors of 387 are 3 x 3 x 43

Prime factors of 761 are 761

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

Given numbers are 156, 225, 387, 761

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

Apply this formula for all numbers.

Step1:

LCM(156, 225) = 11700

GCD(156, 225) = ( 156 x 225 ) / 11700

= 156 / 225

= 156

Step2:

LCM(3, 387) = 387

GCD(3, 387) = ( 3 x 387 ) / 387

= 3 / 387

= 3

Step3:

LCM(3, 761) = 2283

GCD(3, 761) = ( 3 x 761 ) / 2283

= 3 / 761

= 3

So, Greatest Common Divisor of 156, 225, 387, 761 is 1
