Given numbers are 840, 631, 465, 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, 631) = 530040
GCD(840, 631) = ( 840 x 631 ) / 530040
= 840 / 631
= 840
Step2:
LCM(1, 465) = 465
GCD(1, 465) = ( 1 x 465 ) / 465
= 1 / 465
= 1
Step3:
LCM(1, 419) = 419
GCD(1, 419) = ( 1 x 419 ) / 419
= 1 / 419
= 1
So, Greatest Common Divisor of 840, 631, 465, 419 is 1
