Given numbers are 661, 516, 846, 400

The list of prime factors of all numbers are

Prime factors of 661 are 661

Prime factors of 516 are 2 x 2 x 3 x 43

Prime factors of 846 are 2 x 3 x 3 x 47

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

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

Given numbers are 661, 516, 846, 400

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

Apply this formula for all numbers.

Step1:

LCM(661, 516) = 341076

GCD(661, 516) = ( 661 x 516 ) / 341076

= 661 / 516

= 661

Step2:

LCM(1, 846) = 846

GCD(1, 846) = ( 1 x 846 ) / 846

= 1 / 846

= 1

Step3:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1

So, Greatest Common Divisor of 661, 516, 846, 400 is 1
