Given numbers are 551, 320, 195, 378
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(551, 320) = 176320
GCD(551, 320) = ( 551 x 320 ) / 176320
= 551 / 320
= 551
Step2:
LCM(1, 195) = 195
GCD(1, 195) = ( 1 x 195 ) / 195
= 1 / 195
= 1
Step3:
LCM(1, 378) = 378
GCD(1, 378) = ( 1 x 378 ) / 378
= 1 / 378
= 1
So, Greatest Common Divisor of 551, 320, 195, 378 is 1
