GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 788) = 156812
GCD(398, 788) = ( 398 x 788 ) / 156812
= 398 / 788
= 398
Step2:
LCM(2, 542) = 542
GCD(2, 542) = ( 2 x 542 ) / 542
= 2 / 542
= 2
Step3:
LCM(2, 429) = 858
GCD(2, 429) = ( 2 x 429 ) / 858
= 2 / 429
= 2
So, Greatest Common Divisor of 398, 788, 542, 429 is 1
