Given numbers are 805, 425, 868, 406
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(805, 425) = 68425
GCD(805, 425) = ( 805 x 425 ) / 68425
= 805 / 425
= 805
Step2:
LCM(5, 868) = 4340
GCD(5, 868) = ( 5 x 868 ) / 4340
= 5 / 868
= 5
Step3:
LCM(1, 406) = 406
GCD(1, 406) = ( 1 x 406 ) / 406
= 1 / 406
= 1
So, Greatest Common Divisor of 805, 425, 868, 406 is 1
