Given numbers are 126, 170, 767, 661

The list of prime factors of all numbers are

Prime factors of 126 are 2 x 3 x 3 x 7

Prime factors of 170 are 2 x 5 x 17

Prime factors of 767 are 13 x 59

Prime factors of 661 are 661

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

Given numbers are 126, 170, 767, 661

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

Apply this formula for all numbers.

Step1:

LCM(126, 170) = 10710

GCD(126, 170) = ( 126 x 170 ) / 10710

= 126 / 170

= 126

Step2:

LCM(2, 767) = 1534

GCD(2, 767) = ( 2 x 767 ) / 1534

= 2 / 767

= 2

Step3:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

So, Greatest Common Divisor of 126, 170, 767, 661 is 1
