Given numbers are 821, 777, 798, 150

The list of prime factors of all numbers are

Prime factors of 821 are 821

Prime factors of 777 are 3 x 7 x 37

Prime factors of 798 are 2 x 3 x 7 x 19

Prime factors of 150 are 2 x 3 x 5 x 5

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

Given numbers are 821, 777, 798, 150

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

Apply this formula for all numbers.

Step1:

LCM(821, 777) = 637917

GCD(821, 777) = ( 821 x 777 ) / 637917

= 821 / 777

= 821

Step2:

LCM(1, 798) = 798

GCD(1, 798) = ( 1 x 798 ) / 798

= 1 / 798

= 1

Step3:

LCM(1, 150) = 150

GCD(1, 150) = ( 1 x 150 ) / 150

= 1 / 150

= 1

So, Greatest Common Divisor of 821, 777, 798, 150 is 1
