HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 763, 569, 642 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 763, 569, 642 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 763, 569, 642 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 763, 569, 642 is 1.

HCF(763, 569, 642) = 1

HCF of 763, 569, 642 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 763, 569, 642 is 1.

Highest Common Factor of 763,569,642 using Euclid's algorithm

Highest Common Factor of 763,569,642 is 1

Step 1: Since 763 > 569, we apply the division lemma to 763 and 569, to get

763 = 569 x 1 + 194

Step 2: Since the reminder 569 ≠ 0, we apply division lemma to 194 and 569, to get

569 = 194 x 2 + 181

Step 3: We consider the new divisor 194 and the new remainder 181, and apply the division lemma to get

194 = 181 x 1 + 13

We consider the new divisor 181 and the new remainder 13,and apply the division lemma to get

181 = 13 x 13 + 12

We consider the new divisor 13 and the new remainder 12,and apply the division lemma to get

13 = 12 x 1 + 1

We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get

12 = 1 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 763 and 569 is 1

Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(181,13) = HCF(194,181) = HCF(569,194) = HCF(763,569) .


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

Step 1: Since 642 > 1, we apply the division lemma to 642 and 1, to get

642 = 1 x 642 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 642 is 1

Notice that 1 = HCF(642,1) .
