The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 840, 751, 954, 809
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 751) = 630840
GCD(840, 751) = ( 840 x 751 ) / 630840
= 840 / 751
= 840
Step2:
LCM(1, 954) = 954
GCD(1, 954) = ( 1 x 954 ) / 954
= 1 / 954
= 1
Step3:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
So, Greatest Common Divisor of 840, 751, 954, 809 is 1
