Given numbers are 455, 651, 390, 194
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(455, 651) = 42315
GCD(455, 651) = ( 455 x 651 ) / 42315
= 455 / 651
= 455
Step2:
LCM(7, 390) = 2730
GCD(7, 390) = ( 7 x 390 ) / 2730
= 7 / 390
= 7
Step3:
LCM(1, 194) = 194
GCD(1, 194) = ( 1 x 194 ) / 194
= 1 / 194
= 1
So, Greatest Common Divisor of 455, 651, 390, 194 is 1
