Given numbers are 971, 840, 345, 844
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(971, 840) = 815640
GCD(971, 840) = ( 971 x 840 ) / 815640
= 971 / 840
= 971
Step2:
LCM(1, 345) = 345
GCD(1, 345) = ( 1 x 345 ) / 345
= 1 / 345
= 1
Step3:
LCM(1, 844) = 844
GCD(1, 844) = ( 1 x 844 ) / 844
= 1 / 844
= 1
So, Greatest Common Divisor of 971, 840, 345, 844 is 1
