HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 387, 493, 826 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 387, 493, 826 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 387, 493, 826 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 387, 493, 826 is 1.

HCF(387, 493, 826) = 1

Highest common factor (HCF) of 387, 493, 826 is 1.

Highest Common Factor of 387,493,826 using Euclid's algorithm

Highest Common Factor of 387,493,826 is 1

Step 1: Since 493 > 387, we apply the division lemma to 493 and 387, to get

493 = 387 x 1 + 106

Step 2: Since the reminder 387 ≠ 0, we apply division lemma to 106 and 387, to get

387 = 106 x 3 + 69

Step 3: We consider the new divisor 106 and the new remainder 69, and apply the division lemma to get

106 = 69 x 1 + 37

We consider the new divisor 69 and the new remainder 37,and apply the division lemma to get

69 = 37 x 1 + 32

We consider the new divisor 37 and the new remainder 32,and apply the division lemma to get

37 = 32 x 1 + 5

We consider the new divisor 32 and the new remainder 5,and apply the division lemma to get

32 = 5 x 6 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 387 and 493 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(32,5) = HCF(37,32) = HCF(69,37) = HCF(106,69) = HCF(387,106) = HCF(493,387) .

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

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

826 = 1 x 826 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 826 is 1

Notice that 1 = HCF(826,1) .
