GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(345, 639) = 73485
GCD(345, 639) = ( 345 x 639 ) / 73485
= 345 / 639
= 345
Step2:
LCM(3, 303) = 303
GCD(3, 303) = ( 3 x 303 ) / 303
= 3 / 303
= 3
Step3:
LCM(3, 688) = 2064
GCD(3, 688) = ( 3 x 688 ) / 2064
= 3 / 688
= 3
So, Greatest Common Divisor of 345, 639, 303, 688 is 1
