HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 641, 413, 772 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 641, 413, 772 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 641, 413, 772 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 641, 413, 772 is 1.

HCF(641, 413, 772) = 1

Highest common factor (HCF) of 641, 413, 772 is 1.

Highest Common Factor of 641,413,772 using Euclid's algorithm

Highest Common Factor of 641,413,772 is 1

Step 1: Since 641 > 413, we apply the division lemma to 641 and 413, to get

641 = 413 x 1 + 228

Step 2: Since the reminder 413 ≠ 0, we apply division lemma to 228 and 413, to get

413 = 228 x 1 + 185

Step 3: We consider the new divisor 228 and the new remainder 185, and apply the division lemma to get

228 = 185 x 1 + 43

We consider the new divisor 185 and the new remainder 43,and apply the division lemma to get

185 = 43 x 4 + 13

We consider the new divisor 43 and the new remainder 13,and apply the division lemma to get

43 = 13 x 3 + 4

We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get

13 = 4 x 3 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 641 and 413 is 1

Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(43,13) = HCF(185,43) = HCF(228,185) = HCF(413,228) = HCF(641,413) .

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

Step 1: Since 772 > 1, we apply the division lemma to 772 and 1, to get

772 = 1 x 772 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 772 is 1

Notice that 1 = HCF(772,1) .
