Given numbers are 842, 656, 807, 518
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(842, 656) = 276176
GCD(842, 656) = ( 842 x 656 ) / 276176
= 842 / 656
= 842
Step2:
LCM(2, 807) = 1614
GCD(2, 807) = ( 2 x 807 ) / 1614
= 2 / 807
= 2
Step3:
LCM(1, 518) = 518
GCD(1, 518) = ( 1 x 518 ) / 518
= 1 / 518
= 1
So, Greatest Common Divisor of 842, 656, 807, 518 is 1
