Given numbers are 990, 639, 957, 175

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

Apply this formula for all numbers.

Step1:

LCM(990, 639) = 70290

GCD(990, 639) = ( 990 x 639 ) / 70290

= 990 / 639

= 990

Step2:

LCM(9, 957) = 2871

GCD(9, 957) = ( 9 x 957 ) / 2871

= 9 / 957

= 9

Step3:

LCM(3, 175) = 525

GCD(3, 175) = ( 3 x 175 ) / 525

= 3 / 175

= 3

So, Greatest Common Divisor of 990, 639, 957, 175 is 1
