GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 844) = 542692
GCD(643, 844) = ( 643 x 844 ) / 542692
= 643 / 844
= 643
Step2:
LCM(1, 200) = 200
GCD(1, 200) = ( 1 x 200 ) / 200
= 1 / 200
= 1
Step3:
LCM(1, 418) = 418
GCD(1, 418) = ( 1 x 418 ) / 418
= 1 / 418
= 1
So, Greatest Common Divisor of 643, 844, 200, 418 is 1
