Given numbers are 781, 286, 916, 722
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(781, 286) = 20306
GCD(781, 286) = ( 781 x 286 ) / 20306
= 781 / 286
= 781
Step2:
LCM(11, 916) = 10076
GCD(11, 916) = ( 11 x 916 ) / 10076
= 11 / 916
= 11
Step3:
LCM(1, 722) = 722
GCD(1, 722) = ( 1 x 722 ) / 722
= 1 / 722
= 1
So, Greatest Common Divisor of 781, 286, 916, 722 is 1
