GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(318, 832) = 132288
GCD(318, 832) = ( 318 x 832 ) / 132288
= 318 / 832
= 318
Step2:
LCM(2, 891) = 1782
GCD(2, 891) = ( 2 x 891 ) / 1782
= 2 / 891
= 2
Step3:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
So, Greatest Common Divisor of 318, 832, 891, 642 is 1
