Given numbers are 986, 436, 13, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(986, 436) = 214948
GCD(986, 436) = ( 986 x 436 ) / 214948
= 986 / 436
= 986
Step2:
LCM(2, 13) = 26
GCD(2, 13) = ( 2 x 13 ) / 26
= 2 / 13
= 2
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 986, 436, 13, 781 is 1
