HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 438, 987, 446 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 438, 987, 446 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 438, 987, 446 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 438, 987, 446 is 1.

HCF(438, 987, 446) = 1

HCF of 438, 987, 446 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 438, 987, 446 is 1.

Highest Common Factor of 438,987,446 using Euclid's algorithm

Highest Common Factor of 438,987,446 is 1

Step 1: Since 987 > 438, we apply the division lemma to 987 and 438, to get

987 = 438 x 2 + 111

Step 2: Since the reminder 438 ≠ 0, we apply division lemma to 111 and 438, to get

438 = 111 x 3 + 105

Step 3: We consider the new divisor 111 and the new remainder 105, and apply the division lemma to get

111 = 105 x 1 + 6

We consider the new divisor 105 and the new remainder 6,and apply the division lemma to get

105 = 6 x 17 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 438 and 987 is 3

Notice that 3 = HCF(6,3) = HCF(105,6) = HCF(111,105) = HCF(438,111) = HCF(987,438) .

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

Step 1: Since 446 > 3, we apply the division lemma to 446 and 3, to get

446 = 3 x 148 + 2

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get

3 = 2 x 1 + 1

Step 3: 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 3 and 446 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(446,3) .
