Given numbers are 770, 678, 710, 487
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(770, 678) = 261030
GCD(770, 678) = ( 770 x 678 ) / 261030
= 770 / 678
= 770
Step2:
LCM(2, 710) = 710
GCD(2, 710) = ( 2 x 710 ) / 710
= 2 / 710
= 2
Step3:
LCM(2, 487) = 974
GCD(2, 487) = ( 2 x 487 ) / 974
= 2 / 487
= 2
So, Greatest Common Divisor of 770, 678, 710, 487 is 1
