HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 389, 472, 922 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 389, 472, 922 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 389, 472, 922 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 389, 472, 922 is 1.

HCF(389, 472, 922) = 1

Highest common factor (HCF) of 389, 472, 922 is 1.

Highest Common Factor of 389,472,922 using Euclid's algorithm

Highest Common Factor of 389,472,922 is 1

Step 1: Since 472 > 389, we apply the division lemma to 472 and 389, to get

472 = 389 x 1 + 83

Step 2: Since the reminder 389 ≠ 0, we apply division lemma to 83 and 389, to get

389 = 83 x 4 + 57

Step 3: We consider the new divisor 83 and the new remainder 57, and apply the division lemma to get

83 = 57 x 1 + 26

We consider the new divisor 57 and the new remainder 26,and apply the division lemma to get

57 = 26 x 2 + 5

We consider the new divisor 26 and the new remainder 5,and apply the division lemma to get

26 = 5 x 5 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 389 and 472 is 1

Notice that 1 = HCF(5,1) = HCF(26,5) = HCF(57,26) = HCF(83,57) = HCF(389,83) = HCF(472,389) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 922 > 1, we apply the division lemma to 922 and 1, to get

922 = 1 x 922 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 922 is 1

Notice that 1 = HCF(922,1) .
