Given numbers are 688, 824, 770, 153

The list of prime factors of all numbers are

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 824 are 2 x 2 x 2 x 103

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 153 are 3 x 3 x 17

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

Given numbers are 688, 824, 770, 153

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

Apply this formula for all numbers.

Step1:

LCM(688, 824) = 70864

GCD(688, 824) = ( 688 x 824 ) / 70864

= 688 / 824

= 688

Step2:

LCM(8, 770) = 3080

GCD(8, 770) = ( 8 x 770 ) / 3080

= 8 / 770

= 8

Step3:

LCM(2, 153) = 306

GCD(2, 153) = ( 2 x 153 ) / 306

= 2 / 153

= 2

So, Greatest Common Divisor of 688, 824, 770, 153 is 1
