Given numbers are 268, 156, 312, 449
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(268, 156) = 10452
GCD(268, 156) = ( 268 x 156 ) / 10452
= 268 / 156
= 268
Step2:
LCM(4, 312) = 312
GCD(4, 312) = ( 4 x 312 ) / 312
= 4 / 312
= 4
Step3:
LCM(4, 449) = 1796
GCD(4, 449) = ( 4 x 449 ) / 1796
= 4 / 449
= 4
So, Greatest Common Divisor of 268, 156, 312, 449 is 1
