HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 789, 46891 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 789, 46891 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 789, 46891 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 789, 46891 is 1.

HCF(789, 46891) = 1

Highest Common Factor of 789,46891 using Euclid's algorithm

Highest Common Factor of 789,46891 is 1

Step 1: Since 46891 > 789, we apply the division lemma to 46891 and 789, to get

46891 = 789 x 59 + 340

Step 2: Since the reminder 789 ≠ 0, we apply division lemma to 340 and 789, to get

789 = 340 x 2 + 109

Step 3: We consider the new divisor 340 and the new remainder 109, and apply the division lemma to get

340 = 109 x 3 + 13

We consider the new divisor 109 and the new remainder 13,and apply the division lemma to get

109 = 13 x 8 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 789 and 46891 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(109,13) = HCF(340,109) = HCF(789,340) = HCF(46891,789) .
