GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(478, 891) = 425898
GCD(478, 891) = ( 478 x 891 ) / 425898
= 478 / 891
= 478
Step2:
LCM(1, 895) = 895
GCD(1, 895) = ( 1 x 895 ) / 895
= 1 / 895
= 1
Step3:
LCM(1, 340) = 340
GCD(1, 340) = ( 1 x 340 ) / 340
= 1 / 340
= 1
So, Greatest Common Divisor of 478, 891, 895, 340 is 1
