Given numbers are 802, 745, 821, 660

The list of prime factors of all numbers are

Prime factors of 802 are 2 x 401

Prime factors of 745 are 5 x 149

Prime factors of 821 are 821

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

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

Given numbers are 802, 745, 821, 660

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

Apply this formula for all numbers.

Step1:

LCM(802, 745) = 597490

GCD(802, 745) = ( 802 x 745 ) / 597490

= 802 / 745

= 802

Step2:

LCM(1, 821) = 821

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

= 1 / 821

= 1

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 802, 745, 821, 660 is 1
