Given numbers are 455, 310, 219, 636
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(455, 310) = 28210
GCD(455, 310) = ( 455 x 310 ) / 28210
= 455 / 310
= 455
Step2:
LCM(5, 219) = 1095
GCD(5, 219) = ( 5 x 219 ) / 1095
= 5 / 219
= 5
Step3:
LCM(1, 636) = 636
GCD(1, 636) = ( 1 x 636 ) / 636
= 1 / 636
= 1
So, Greatest Common Divisor of 455, 310, 219, 636 is 1
