Given numbers are 720, 926, 921, 857
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(720, 926) = 333360
GCD(720, 926) = ( 720 x 926 ) / 333360
= 720 / 926
= 720
Step2:
LCM(2, 921) = 1842
GCD(2, 921) = ( 2 x 921 ) / 1842
= 2 / 921
= 2
Step3:
LCM(1, 857) = 857
GCD(1, 857) = ( 1 x 857 ) / 857
= 1 / 857
= 1
So, Greatest Common Divisor of 720, 926, 921, 857 is 1
