HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 742, 826, 909 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 742, 826, 909 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 742, 826, 909 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 742, 826, 909 is 1.

HCF(742, 826, 909) = 1

HCF of 742, 826, 909 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 742, 826, 909 is 1.

Highest Common Factor of 742,826,909 using Euclid's algorithm

Highest Common Factor of 742,826,909 is 1

Step 1: Since 826 > 742, we apply the division lemma to 826 and 742, to get

826 = 742 x 1 + 84

Step 2: Since the reminder 742 ≠ 0, we apply division lemma to 84 and 742, to get

742 = 84 x 8 + 70

Step 3: We consider the new divisor 84 and the new remainder 70, and apply the division lemma to get

84 = 70 x 1 + 14

We consider the new divisor 70 and the new remainder 14, and apply the division lemma to get

70 = 14 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 742 and 826 is 14

Notice that 14 = HCF(70,14) = HCF(84,70) = HCF(742,84) = HCF(826,742) .

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

Step 1: Since 909 > 14, we apply the division lemma to 909 and 14, to get

909 = 14 x 64 + 13

Step 2: Since the reminder 14 ≠ 0, we apply division lemma to 13 and 14, to get

14 = 13 x 1 + 1

Step 3: We consider the new divisor 13 and the new remainder 1, and apply the division lemma to get

13 = 1 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 14 and 909 is 1

Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(909,14) .
