Given numbers are 312, 647, 424, 204
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(312, 647) = 201864
GCD(312, 647) = ( 312 x 647 ) / 201864
= 312 / 647
= 312
Step2:
LCM(1, 424) = 424
GCD(1, 424) = ( 1 x 424 ) / 424
= 1 / 424
= 1
Step3:
LCM(1, 204) = 204
GCD(1, 204) = ( 1 x 204 ) / 204
= 1 / 204
= 1
So, Greatest Common Divisor of 312, 647, 424, 204 is 1
