Given numbers are 868, 400, 758, 620
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(868, 400) = 86800
GCD(868, 400) = ( 868 x 400 ) / 86800
= 868 / 400
= 868
Step2:
LCM(4, 758) = 1516
GCD(4, 758) = ( 4 x 758 ) / 1516
= 4 / 758
= 4
Step3:
LCM(2, 620) = 620
GCD(2, 620) = ( 2 x 620 ) / 620
= 2 / 620
= 2
So, Greatest Common Divisor of 868, 400, 758, 620 is 2
