Given numbers are 402, 406, 898, 991
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(402, 406) = 81606
GCD(402, 406) = ( 402 x 406 ) / 81606
= 402 / 406
= 402
Step2:
LCM(2, 898) = 898
GCD(2, 898) = ( 2 x 898 ) / 898
= 2 / 898
= 2
Step3:
LCM(2, 991) = 1982
GCD(2, 991) = ( 2 x 991 ) / 1982
= 2 / 991
= 2
So, Greatest Common Divisor of 402, 406, 898, 991 is 1
