HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 785, 474, 633 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 785, 474, 633 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 785, 474, 633 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 785, 474, 633 is 1.

HCF(785, 474, 633) = 1

HCF of 785, 474, 633 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 785, 474, 633 is 1.

Highest Common Factor of 785,474,633 using Euclid's algorithm

Highest Common Factor of 785,474,633 is 1

Step 1: Since 785 > 474, we apply the division lemma to 785 and 474, to get

785 = 474 x 1 + 311

Step 2: Since the reminder 474 ≠ 0, we apply division lemma to 311 and 474, to get

474 = 311 x 1 + 163

Step 3: We consider the new divisor 311 and the new remainder 163, and apply the division lemma to get

311 = 163 x 1 + 148

We consider the new divisor 163 and the new remainder 148,and apply the division lemma to get

163 = 148 x 1 + 15

We consider the new divisor 148 and the new remainder 15,and apply the division lemma to get

148 = 15 x 9 + 13

We consider the new divisor 15 and the new remainder 13,and apply the division lemma to get

15 = 13 x 1 + 2

We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get

13 = 2 x 6 + 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 785 and 474 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(148,15) = HCF(163,148) = HCF(311,163) = HCF(474,311) = HCF(785,474) .

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

Step 1: Since 633 > 1, we apply the division lemma to 633 and 1, to get

633 = 1 x 633 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 633 is 1

Notice that 1 = HCF(633,1) .
