Given numbers are 661, 146, 308, 351
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(661, 146) = 96506
GCD(661, 146) = ( 661 x 146 ) / 96506
= 661 / 146
= 661
Step2:
LCM(1, 308) = 308
GCD(1, 308) = ( 1 x 308 ) / 308
= 1 / 308
= 1
Step3:
LCM(1, 351) = 351
GCD(1, 351) = ( 1 x 351 ) / 351
= 1 / 351
= 1
So, Greatest Common Divisor of 661, 146, 308, 351 is 1
