Given numbers are 845, 458, 974, 478
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(845, 458) = 387010
GCD(845, 458) = ( 845 x 458 ) / 387010
= 845 / 458
= 845
Step2:
LCM(1, 974) = 974
GCD(1, 974) = ( 1 x 974 ) / 974
= 1 / 974
= 1
Step3:
LCM(1, 478) = 478
GCD(1, 478) = ( 1 x 478 ) / 478
= 1 / 478
= 1
So, Greatest Common Divisor of 845, 458, 974, 478 is 1
