Given numbers are 775, 490, 727, 820
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(775, 490) = 75950
GCD(775, 490) = ( 775 x 490 ) / 75950
= 775 / 490
= 775
Step2:
LCM(5, 727) = 3635
GCD(5, 727) = ( 5 x 727 ) / 3635
= 5 / 727
= 5
Step3:
LCM(1, 820) = 820
GCD(1, 820) = ( 1 x 820 ) / 820
= 1 / 820
= 1
So, Greatest Common Divisor of 775, 490, 727, 820 is 1
