GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(717, 990) = 236610
GCD(717, 990) = ( 717 x 990 ) / 236610
= 717 / 990
= 717
Step2:
LCM(3, 173) = 519
GCD(3, 173) = ( 3 x 173 ) / 519
= 3 / 173
= 3
Step3:
LCM(1, 544) = 544
GCD(1, 544) = ( 1 x 544 ) / 544
= 1 / 544
= 1
So, Greatest Common Divisor of 717, 990, 173, 544 is 1
