HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 540, 894, 478 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 540, 894, 478 is 2 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 540, 894, 478 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 540, 894, 478 is 2.

HCF(540, 894, 478) = 2

Highest common factor (HCF) of 540, 894, 478 is 2.

Highest Common Factor of 540,894,478 using Euclid's algorithm

Highest Common Factor of 540,894,478 is 2

Step 1: Since 894 > 540, we apply the division lemma to 894 and 540, to get

894 = 540 x 1 + 354

Step 2: Since the reminder 540 ≠ 0, we apply division lemma to 354 and 540, to get

540 = 354 x 1 + 186

Step 3: We consider the new divisor 354 and the new remainder 186, and apply the division lemma to get

354 = 186 x 1 + 168

We consider the new divisor 186 and the new remainder 168,and apply the division lemma to get

186 = 168 x 1 + 18

We consider the new divisor 168 and the new remainder 18,and apply the division lemma to get

168 = 18 x 9 + 6

We consider the new divisor 18 and the new remainder 6,and apply the division lemma to get

18 = 6 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 540 and 894 is 6

Notice that 6 = HCF(18,6) = HCF(168,18) = HCF(186,168) = HCF(354,186) = HCF(540,354) = HCF(894,540) .

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

Step 1: Since 478 > 6, we apply the division lemma to 478 and 6, to get

478 = 6 x 79 + 4

Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 4 and 6, to get

6 = 4 x 1 + 2

Step 3: We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 6 and 478 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(478,6) .
