Given numbers are 840, 425, 626, 446
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 425) = 71400
GCD(840, 425) = ( 840 x 425 ) / 71400
= 840 / 425
= 840
Step2:
LCM(5, 626) = 3130
GCD(5, 626) = ( 5 x 626 ) / 3130
= 5 / 626
= 5
Step3:
LCM(1, 446) = 446
GCD(1, 446) = ( 1 x 446 ) / 446
= 1 / 446
= 1
So, Greatest Common Divisor of 840, 425, 626, 446 is 1
