GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(207, 870) = 60030
GCD(207, 870) = ( 207 x 870 ) / 60030
= 207 / 870
= 207
Step2:
LCM(3, 769) = 2307
GCD(3, 769) = ( 3 x 769 ) / 2307
= 3 / 769
= 3
Step3:
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
= 1 / 981
= 1
So, Greatest Common Divisor of 207, 870, 769, 981 is 1
