HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 747, 948, 635 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 747, 948, 635 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 747, 948, 635 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 747, 948, 635 is 1.

HCF(747, 948, 635) = 1

Highest common factor (HCF) of 747, 948, 635 is 1.

Highest Common Factor of 747,948,635 using Euclid's algorithm

Highest Common Factor of 747,948,635 is 1

Step 1: Since 948 > 747, we apply the division lemma to 948 and 747, to get

948 = 747 x 1 + 201

Step 2: Since the reminder 747 ≠ 0, we apply division lemma to 201 and 747, to get

747 = 201 x 3 + 144

Step 3: We consider the new divisor 201 and the new remainder 144, and apply the division lemma to get

201 = 144 x 1 + 57

We consider the new divisor 144 and the new remainder 57,and apply the division lemma to get

144 = 57 x 2 + 30

We consider the new divisor 57 and the new remainder 30,and apply the division lemma to get

57 = 30 x 1 + 27

We consider the new divisor 30 and the new remainder 27,and apply the division lemma to get

30 = 27 x 1 + 3

We consider the new divisor 27 and the new remainder 3,and apply the division lemma to get

27 = 3 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 747 and 948 is 3

Notice that 3 = HCF(27,3) = HCF(30,27) = HCF(57,30) = HCF(144,57) = HCF(201,144) = HCF(747,201) = HCF(948,747) .

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

Step 1: Since 635 > 3, we apply the division lemma to 635 and 3, to get

635 = 3 x 211 + 2

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

3 = 2 x 1 + 1

Step 3: 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 3 and 635 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(635,3) .
