HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 643, 886, 729, 701 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 643, 886, 729, 701 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 643, 886, 729, 701 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 643, 886, 729, 701 is 1.

HCF(643, 886, 729, 701) = 1

Highest Common Factor of 643,886,729,701 using Euclid's algorithm

Highest Common Factor of 643,886,729,701 is 1

Step 1: Since 886 > 643, we apply the division lemma to 886 and 643, to get

886 = 643 x 1 + 243

Step 2: Since the reminder 643 ≠ 0, we apply division lemma to 243 and 643, to get

643 = 243 x 2 + 157

Step 3: We consider the new divisor 243 and the new remainder 157, and apply the division lemma to get

243 = 157 x 1 + 86

We consider the new divisor 157 and the new remainder 86,and apply the division lemma to get

157 = 86 x 1 + 71

We consider the new divisor 86 and the new remainder 71,and apply the division lemma to get

86 = 71 x 1 + 15

We consider the new divisor 71 and the new remainder 15,and apply the division lemma to get

71 = 15 x 4 + 11

We consider the new divisor 15 and the new remainder 11,and apply the division lemma to get

15 = 11 x 1 + 4

We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get

11 = 4 x 2 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

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 643 and 886 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(15,11) = HCF(71,15) = HCF(86,71) = HCF(157,86) = HCF(243,157) = HCF(643,243) = HCF(886,643) .

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

Step 1: Since 729 > 1, we apply the division lemma to 729 and 1, to get

729 = 1 x 729 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 729 is 1

Notice that 1 = HCF(729,1) .

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

Step 1: Since 701 > 1, we apply the division lemma to 701 and 1, to get

701 = 1 x 701 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 701 is 1

Notice that 1 = HCF(701,1) .
