Given numbers are 308, 429, 272, 664
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(308, 429) = 12012
GCD(308, 429) = ( 308 x 429 ) / 12012
= 308 / 429
= 308
Step2:
LCM(11, 272) = 2992
GCD(11, 272) = ( 11 x 272 ) / 2992
= 11 / 272
= 11
Step3:
LCM(1, 664) = 664
GCD(1, 664) = ( 1 x 664 ) / 664
= 1 / 664
= 1
So, Greatest Common Divisor of 308, 429, 272, 664 is 1
