Given numbers are 845, 220, 510, 343
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(845, 220) = 37180
GCD(845, 220) = ( 845 x 220 ) / 37180
= 845 / 220
= 845
Step2:
LCM(5, 510) = 510
GCD(5, 510) = ( 5 x 510 ) / 510
= 5 / 510
= 5
Step3:
LCM(5, 343) = 1715
GCD(5, 343) = ( 5 x 343 ) / 1715
= 5 / 343
= 5
So, Greatest Common Divisor of 845, 220, 510, 343 is 1
