Given numbers are 781, 220, 829, 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, 220) = 15620
GCD(781, 220) = ( 781 x 220 ) / 15620
= 781 / 220
= 781
Step2:
LCM(11, 829) = 9119
GCD(11, 829) = ( 11 x 829 ) / 9119
= 11 / 829
= 11
Step3:
LCM(1, 722) = 722
GCD(1, 722) = ( 1 x 722 ) / 722
= 1 / 722
= 1
So, Greatest Common Divisor of 781, 220, 829, 722 is 1
