Given numbers are 520, 673, 28, 814
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(520, 673) = 349960
GCD(520, 673) = ( 520 x 673 ) / 349960
= 520 / 673
= 520
Step2:
LCM(1, 28) = 28
GCD(1, 28) = ( 1 x 28 ) / 28
= 1 / 28
= 1
Step3:
LCM(1, 814) = 814
GCD(1, 814) = ( 1 x 814 ) / 814
= 1 / 814
= 1
So, Greatest Common Divisor of 520, 673, 28, 814 is 1
