Given numbers are 770, 258, 711, 828
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(770, 258) = 99330
GCD(770, 258) = ( 770 x 258 ) / 99330
= 770 / 258
= 770
Step2:
LCM(2, 711) = 1422
GCD(2, 711) = ( 2 x 711 ) / 1422
= 2 / 711
= 2
Step3:
LCM(1, 828) = 828
GCD(1, 828) = ( 1 x 828 ) / 828
= 1 / 828
= 1
So, Greatest Common Divisor of 770, 258, 711, 828 is 1
