Given numbers are 828, 897, 419, 820
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(828, 897) = 10764
GCD(828, 897) = ( 828 x 897 ) / 10764
= 828 / 897
= 828
Step2:
LCM(69, 419) = 28911
GCD(69, 419) = ( 69 x 419 ) / 28911
= 69 / 419
= 69
Step3:
LCM(1, 820) = 820
GCD(1, 820) = ( 1 x 820 ) / 820
= 1 / 820
= 1
So, Greatest Common Divisor of 828, 897, 419, 820 is 1
