Given numbers are 684, 219, 624, 521
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(684, 219) = 49932
GCD(684, 219) = ( 684 x 219 ) / 49932
= 684 / 219
= 684
Step2:
LCM(3, 624) = 624
GCD(3, 624) = ( 3 x 624 ) / 624
= 3 / 624
= 3
Step3:
LCM(3, 521) = 1563
GCD(3, 521) = ( 3 x 521 ) / 1563
= 3 / 521
= 3
So, Greatest Common Divisor of 684, 219, 624, 521 is 1
