Given numbers are 814, 781, 409, 915
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(814, 781) = 57794
GCD(814, 781) = ( 814 x 781 ) / 57794
= 814 / 781
= 814
Step2:
LCM(11, 409) = 4499
GCD(11, 409) = ( 11 x 409 ) / 4499
= 11 / 409
= 11
Step3:
LCM(1, 915) = 915
GCD(1, 915) = ( 1 x 915 ) / 915
= 1 / 915
= 1
So, Greatest Common Divisor of 814, 781, 409, 915 is 1
