Given numbers are 861, 160, 780, 762

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 160 are 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 762 are 2 x 3 x 127

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

Given numbers are 861, 160, 780, 762

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

Apply this formula for all numbers.

Step1:

LCM(861, 160) = 137760

GCD(861, 160) = ( 861 x 160 ) / 137760

= 861 / 160

= 861

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 762) = 762

GCD(1, 762) = ( 1 x 762 ) / 762

= 1 / 762

= 1

So, Greatest Common Divisor of 861, 160, 780, 762 is 1
