GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(555, 280) = 31080
GCD(555, 280) = ( 555 x 280 ) / 31080
= 555 / 280
= 555
Step2:
LCM(5, 790) = 790
GCD(5, 790) = ( 5 x 790 ) / 790
= 5 / 790
= 5
Step3:
LCM(5, 820) = 820
GCD(5, 820) = ( 5 x 820 ) / 820
= 5 / 820
= 5
So, Greatest Common Divisor of 555, 280, 790, 820 is 5
