HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 700, 412, 391 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 700, 412, 391 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 700, 412, 391 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 700, 412, 391 is 1.

HCF(700, 412, 391) = 1

Highest Common Factor of 700,412,391 using Euclid's algorithm

Highest Common Factor of 700,412,391 is 1

Step 1: Since 700 > 412, we apply the division lemma to 700 and 412, to get

700 = 412 x 1 + 288

Step 2: Since the reminder 412 ≠ 0, we apply division lemma to 288 and 412, to get

412 = 288 x 1 + 124

Step 3: We consider the new divisor 288 and the new remainder 124, and apply the division lemma to get

288 = 124 x 2 + 40

We consider the new divisor 124 and the new remainder 40,and apply the division lemma to get

124 = 40 x 3 + 4

We consider the new divisor 40 and the new remainder 4,and apply the division lemma to get

40 = 4 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 700 and 412 is 4

Notice that 4 = HCF(40,4) = HCF(124,40) = HCF(288,124) = HCF(412,288) = HCF(700,412) .

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

Step 1: Since 391 > 4, we apply the division lemma to 391 and 4, to get

391 = 4 x 97 + 3

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get

4 = 3 x 1 + 1

Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 391 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(391,4) .
