HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 841, 618, 757 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 841, 618, 757 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 841, 618, 757 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 841, 618, 757 is 1.

HCF(841, 618, 757) = 1

HCF of 841, 618, 757 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 841, 618, 757 is 1.

Highest Common Factor of 841,618,757 using Euclid's algorithm

Highest Common Factor of 841,618,757 is 1

Step 1: Since 841 > 618, we apply the division lemma to 841 and 618, to get

841 = 618 x 1 + 223

Step 2: Since the reminder 618 ≠ 0, we apply division lemma to 223 and 618, to get

618 = 223 x 2 + 172

Step 3: We consider the new divisor 223 and the new remainder 172, and apply the division lemma to get

223 = 172 x 1 + 51

We consider the new divisor 172 and the new remainder 51,and apply the division lemma to get

172 = 51 x 3 + 19

We consider the new divisor 51 and the new remainder 19,and apply the division lemma to get

51 = 19 x 2 + 13

We consider the new divisor 19 and the new remainder 13,and apply the division lemma to get

19 = 13 x 1 + 6

We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get

13 = 6 x 2 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 841 and 618 is 1

Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(19,13) = HCF(51,19) = HCF(172,51) = HCF(223,172) = HCF(618,223) = HCF(841,618) .

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

Step 1: Since 757 > 1, we apply the division lemma to 757 and 1, to get

757 = 1 x 757 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 757 is 1

Notice that 1 = HCF(757,1) .
