Given numbers are 455, 346, 513, 220
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(455, 346) = 157430
GCD(455, 346) = ( 455 x 346 ) / 157430
= 455 / 346
= 455
Step2:
LCM(1, 513) = 513
GCD(1, 513) = ( 1 x 513 ) / 513
= 1 / 513
= 1
Step3:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
So, Greatest Common Divisor of 455, 346, 513, 220 is 1
