Given numbers are 324, 644, 149, 917

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

Apply this formula for all numbers.

Step1:

LCM(324, 644) = 52164

GCD(324, 644) = ( 324 x 644 ) / 52164

= 324 / 644

= 324

Step2:

LCM(4, 149) = 596

GCD(4, 149) = ( 4 x 149 ) / 596

= 4 / 149

= 4

Step3:

LCM(1, 917) = 917

GCD(1, 917) = ( 1 x 917 ) / 917

= 1 / 917

= 1

So, Greatest Common Divisor of 324, 644, 149, 917 is 1
