Given numbers are 981, 429, 698, 699
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 429) = 140283
GCD(981, 429) = ( 981 x 429 ) / 140283
= 981 / 429
= 981
Step2:
LCM(3, 698) = 2094
GCD(3, 698) = ( 3 x 698 ) / 2094
= 3 / 698
= 3
Step3:
LCM(1, 699) = 699
GCD(1, 699) = ( 1 x 699 ) / 699
= 1 / 699
= 1
So, Greatest Common Divisor of 981, 429, 698, 699 is 1
