Given numbers are 970, 690, 628, 550

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

Apply this formula for all numbers.

Step1:

LCM(970, 690) = 66930

GCD(970, 690) = ( 970 x 690 ) / 66930

= 970 / 690

= 970

Step2:

LCM(10, 628) = 3140

GCD(10, 628) = ( 10 x 628 ) / 3140

= 10 / 628

= 10

Step3:

LCM(2, 550) = 550

GCD(2, 550) = ( 2 x 550 ) / 550

= 2 / 550

= 2

So, Greatest Common Divisor of 970, 690, 628, 550 is 2
