Given numbers are 805, 156, 402, 977

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

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

Prime factors of 402 are 2 x 3 x 67

Prime factors of 977 are 977

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

Given numbers are 805, 156, 402, 977

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

Apply this formula for all numbers.

Step1:

LCM(805, 156) = 125580

GCD(805, 156) = ( 805 x 156 ) / 125580

= 805 / 156

= 805

Step2:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1

Step3:

LCM(1, 977) = 977

GCD(1, 977) = ( 1 x 977 ) / 977

= 1 / 977

= 1

So, Greatest Common Divisor of 805, 156, 402, 977 is 1
