Given numbers are 770, 220, 19
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(770, 220) = 1540
GCD(770, 220) = ( 770 x 220 ) / 1540
= 770 / 220
= 770
Step2:
LCM(110, 19) = 2090
GCD(110, 19) = ( 110 x 19 ) / 2090
= 110 / 19
= 110
So, Greatest Common Divisor of 770, 220, 19 is 1
