Given numbers are 520, 726, 421
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(520, 726) = 188760
GCD(520, 726) = ( 520 x 726 ) / 188760
= 520 / 726
= 520
Step2:
LCM(2, 421) = 842
GCD(2, 421) = ( 2 x 421 ) / 842
= 2 / 421
= 2
So, Greatest Common Divisor of 520, 726, 421 is 1
