Given numbers are 840, 422, 486, 419
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 422) = 177240
GCD(840, 422) = ( 840 x 422 ) / 177240
= 840 / 422
= 840
Step2:
LCM(2, 486) = 486
GCD(2, 486) = ( 2 x 486 ) / 486
= 2 / 486
= 2
Step3:
LCM(2, 419) = 838
GCD(2, 419) = ( 2 x 419 ) / 838
= 2 / 419
= 2
So, Greatest Common Divisor of 840, 422, 486, 419 is 1
