Given numbers are 406, 144, 778, 419
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(406, 144) = 29232
GCD(406, 144) = ( 406 x 144 ) / 29232
= 406 / 144
= 406
Step2:
LCM(2, 778) = 778
GCD(2, 778) = ( 2 x 778 ) / 778
= 2 / 778
= 2
Step3:
LCM(2, 419) = 838
GCD(2, 419) = ( 2 x 419 ) / 838
= 2 / 419
= 2
So, Greatest Common Divisor of 406, 144, 778, 419 is 1
