GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(868, 391) = 339388
GCD(868, 391) = ( 868 x 391 ) / 339388
= 868 / 391
= 868
Step2:
LCM(1, 433) = 433
GCD(1, 433) = ( 1 x 433 ) / 433
= 1 / 433
= 1
Step3:
LCM(1, 980) = 980
GCD(1, 980) = ( 1 x 980 ) / 980
= 1 / 980
= 1
So, Greatest Common Divisor of 868, 391, 433, 980 is 1
