Given numbers are 424, 822, 403, 155
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(424, 822) = 174264
GCD(424, 822) = ( 424 x 822 ) / 174264
= 424 / 822
= 424
Step2:
LCM(2, 403) = 806
GCD(2, 403) = ( 2 x 403 ) / 806
= 2 / 403
= 2
Step3:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
So, Greatest Common Divisor of 424, 822, 403, 155 is 1
