GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(808, 916) = 185032
GCD(808, 916) = ( 808 x 916 ) / 185032
= 808 / 916
= 808
Step2:
LCM(4, 780) = 780
GCD(4, 780) = ( 4 x 780 ) / 780
= 4 / 780
= 4
Step3:
LCM(4, 423) = 1692
GCD(4, 423) = ( 4 x 423 ) / 1692
= 4 / 423
= 4
So, Greatest Common Divisor of 808, 916, 780, 423 is 1
