Given numbers are 716, 858, 839, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(716, 858) = 307164
GCD(716, 858) = ( 716 x 858 ) / 307164
= 716 / 858
= 716
Step2:
LCM(2, 839) = 1678
GCD(2, 839) = ( 2 x 839 ) / 1678
= 2 / 839
= 2
Step3:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
So, Greatest Common Divisor of 716, 858, 839, 643 is 1
