GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(126, 369) = 5166
GCD(126, 369) = ( 126 x 369 ) / 5166
= 126 / 369
= 126
Step2:
LCM(9, 858) = 2574
GCD(9, 858) = ( 9 x 858 ) / 2574
= 9 / 858
= 9
Step3:
LCM(3, 688) = 2064
GCD(3, 688) = ( 3 x 688 ) / 2064
= 3 / 688
= 3
So, Greatest Common Divisor of 126, 369, 858, 688 is 1
