Given numbers are 408, 272, 915, 814
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(408, 272) = 816
GCD(408, 272) = ( 408 x 272 ) / 816
= 408 / 272
= 408
Step2:
LCM(136, 915) = 124440
GCD(136, 915) = ( 136 x 915 ) / 124440
= 136 / 915
= 136
Step3:
LCM(1, 814) = 814
GCD(1, 814) = ( 1 x 814 ) / 814
= 1 / 814
= 1
So, Greatest Common Divisor of 408, 272, 915, 814 is 1
