Given numbers are 624, 647, 399, 415
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(624, 647) = 403728
GCD(624, 647) = ( 624 x 647 ) / 403728
= 624 / 647
= 624
Step2:
LCM(1, 399) = 399
GCD(1, 399) = ( 1 x 399 ) / 399
= 1 / 399
= 1
Step3:
LCM(1, 415) = 415
GCD(1, 415) = ( 1 x 415 ) / 415
= 1 / 415
= 1
So, Greatest Common Divisor of 624, 647, 399, 415 is 1
