Given numbers are 802, 138, 775, 147

The list of prime factors of all numbers are

Prime factors of 802 are 2 x 401

Prime factors of 138 are 2 x 3 x 23

Prime factors of 775 are 5 x 5 x 31

Prime factors of 147 are 3 x 7 x 7

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

Given numbers are 802, 138, 775, 147

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

Apply this formula for all numbers.

Step1:

LCM(802, 138) = 55338

GCD(802, 138) = ( 802 x 138 ) / 55338

= 802 / 138

= 802

Step2:

LCM(2, 775) = 1550

GCD(2, 775) = ( 2 x 775 ) / 1550

= 2 / 775

= 2

Step3:

LCM(1, 147) = 147

GCD(1, 147) = ( 1 x 147 ) / 147

= 1 / 147

= 1

So, Greatest Common Divisor of 802, 138, 775, 147 is 1
