Given numbers are 770, 987, 353, 721
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(770, 987) = 108570
GCD(770, 987) = ( 770 x 987 ) / 108570
= 770 / 987
= 770
Step2:
LCM(7, 353) = 2471
GCD(7, 353) = ( 7 x 353 ) / 2471
= 7 / 353
= 7
Step3:
LCM(1, 721) = 721
GCD(1, 721) = ( 1 x 721 ) / 721
= 1 / 721
= 1
So, Greatest Common Divisor of 770, 987, 353, 721 is 1
