GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(659, 479) = 315661
GCD(659, 479) = ( 659 x 479 ) / 315661
= 659 / 479
= 659
Step2:
LCM(1, 443) = 443
GCD(1, 443) = ( 1 x 443 ) / 443
= 1 / 443
= 1
Step3:
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
= 1 / 840
= 1
So, Greatest Common Divisor of 659, 479, 443, 840 is 1
