Given numbers are 820, 152, 307, 821

The list of prime factors of all numbers are

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 152 are 2 x 2 x 2 x 19

Prime factors of 307 are 307

Prime factors of 821 are 821

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

Given numbers are 820, 152, 307, 821

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

Apply this formula for all numbers.

Step1:

LCM(820, 152) = 31160

GCD(820, 152) = ( 820 x 152 ) / 31160

= 820 / 152

= 820

Step2:

LCM(4, 307) = 1228

GCD(4, 307) = ( 4 x 307 ) / 1228

= 4 / 307

= 4

Step3:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

So, Greatest Common Divisor of 820, 152, 307, 821 is 1
