Given numbers are 455, 318, 290, 462
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(455, 318) = 144690
GCD(455, 318) = ( 455 x 318 ) / 144690
= 455 / 318
= 455
Step2:
LCM(1, 290) = 290
GCD(1, 290) = ( 1 x 290 ) / 290
= 1 / 290
= 1
Step3:
LCM(1, 462) = 462
GCD(1, 462) = ( 1 x 462 ) / 462
= 1 / 462
= 1
So, Greatest Common Divisor of 455, 318, 290, 462 is 1
