GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(124, 998) = 61876
GCD(124, 998) = ( 124 x 998 ) / 61876
= 124 / 998
= 124
Step2:
LCM(2, 642) = 642
GCD(2, 642) = ( 2 x 642 ) / 642
= 2 / 642
= 2
Step3:
LCM(2, 705) = 1410
GCD(2, 705) = ( 2 x 705 ) / 1410
= 2 / 705
= 2
So, Greatest Common Divisor of 124, 998, 642, 705 is 1
