Given numbers are 706, 780, 370, 989

The list of prime factors of all numbers are

Prime factors of 706 are 2 x 353

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 370 are 2 x 5 x 37

Prime factors of 989 are 23 x 43

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

Given numbers are 706, 780, 370, 989

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

Apply this formula for all numbers.

Step1:

LCM(706, 780) = 275340

GCD(706, 780) = ( 706 x 780 ) / 275340

= 706 / 780

= 706

Step2:

LCM(2, 370) = 370

GCD(2, 370) = ( 2 x 370 ) / 370

= 2 / 370

= 2

Step3:

LCM(2, 989) = 1978

GCD(2, 989) = ( 2 x 989 ) / 1978

= 2 / 989

= 2

So, Greatest Common Divisor of 706, 780, 370, 989 is 1
