GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(826, 800) = 330400
GCD(826, 800) = ( 826 x 800 ) / 330400
= 826 / 800
= 826
Step2:
LCM(2, 420) = 420
GCD(2, 420) = ( 2 x 420 ) / 420
= 2 / 420
= 2
Step3:
LCM(2, 478) = 478
GCD(2, 478) = ( 2 x 478 ) / 478
= 2 / 478
= 2
So, Greatest Common Divisor of 826, 800, 420, 478 is 2
