Given numbers are 449, 163, 340, 458
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(449, 163) = 73187
GCD(449, 163) = ( 449 x 163 ) / 73187
= 449 / 163
= 449
Step2:
LCM(1, 340) = 340
GCD(1, 340) = ( 1 x 340 ) / 340
= 1 / 340
= 1
Step3:
LCM(1, 458) = 458
GCD(1, 458) = ( 1 x 458 ) / 458
= 1 / 458
= 1
So, Greatest Common Divisor of 449, 163, 340, 458 is 1
