Given numbers are 646, 953, 670

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

Apply this formula for all numbers.

Step1:

LCM(646, 953) = 615638

GCD(646, 953) = ( 646 x 953 ) / 615638

= 646 / 953

= 646

Step2:

LCM(1, 670) = 670

GCD(1, 670) = ( 1 x 670 ) / 670

= 1 / 670

= 1

So, Greatest Common Divisor of 646, 953, 670 is 1
