Given numbers are 646, 670, 368, 955

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

Apply this formula for all numbers.

Step1:

LCM(646, 670) = 216410

GCD(646, 670) = ( 646 x 670 ) / 216410

= 646 / 670

= 646

Step2:

LCM(2, 368) = 368

GCD(2, 368) = ( 2 x 368 ) / 368

= 2 / 368

= 2

Step3:

LCM(2, 955) = 1910

GCD(2, 955) = ( 2 x 955 ) / 1910

= 2 / 955

= 2

So, Greatest Common Divisor of 646, 670, 368, 955 is 1
