Given numbers are 862, 343, 13, 455
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(862, 343) = 295666
GCD(862, 343) = ( 862 x 343 ) / 295666
= 862 / 343
= 862
Step2:
LCM(1, 13) = 13
GCD(1, 13) = ( 1 x 13 ) / 13
= 1 / 13
= 1
Step3:
LCM(1, 455) = 455
GCD(1, 455) = ( 1 x 455 ) / 455
= 1 / 455
= 1
So, Greatest Common Divisor of 862, 343, 13, 455 is 1
