Given numbers are 140, 770, 489, 612

The list of prime factors of all numbers are

Prime factors of 140 are 2 x 2 x 5 x 7

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

Prime factors of 489 are 3 x 163

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

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

Given numbers are 140, 770, 489, 612

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

Apply this formula for all numbers.

Step1:

LCM(140, 770) = 1540

GCD(140, 770) = ( 140 x 770 ) / 1540

= 140 / 770

= 140

Step2:

LCM(70, 489) = 34230

GCD(70, 489) = ( 70 x 489 ) / 34230

= 70 / 489

= 70

Step3:

LCM(1, 612) = 612

GCD(1, 612) = ( 1 x 612 ) / 612

= 1 / 612

= 1

So, Greatest Common Divisor of 140, 770, 489, 612 is 1
