Given numbers are 620, 628, 825
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 628) = 97340
GCD(620, 628) = ( 620 x 628 ) / 97340
= 620 / 628
= 620
Step2:
LCM(4, 825) = 3300
GCD(4, 825) = ( 4 x 825 ) / 3300
= 4 / 825
= 4
So, Greatest Common Divisor of 620, 628, 825 is 1
