Given numbers are 661, 551, 578, 326
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(661, 551) = 364211
GCD(661, 551) = ( 661 x 551 ) / 364211
= 661 / 551
= 661
Step2:
LCM(1, 578) = 578
GCD(1, 578) = ( 1 x 578 ) / 578
= 1 / 578
= 1
Step3:
LCM(1, 326) = 326
GCD(1, 326) = ( 1 x 326 ) / 326
= 1 / 326
= 1
So, Greatest Common Divisor of 661, 551, 578, 326 is 1
