Given numbers are 490, 255, 461, 378
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(490, 255) = 24990
GCD(490, 255) = ( 490 x 255 ) / 24990
= 490 / 255
= 490
Step2:
LCM(5, 461) = 2305
GCD(5, 461) = ( 5 x 461 ) / 2305
= 5 / 461
= 5
Step3:
LCM(1, 378) = 378
GCD(1, 378) = ( 1 x 378 ) / 378
= 1 / 378
= 1
So, Greatest Common Divisor of 490, 255, 461, 378 is 1
