HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 477, 365, 474 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 477, 365, 474 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 477, 365, 474 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 477, 365, 474 is 1.

HCF(477, 365, 474) = 1

HCF of 477, 365, 474 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 477, 365, 474 is 1.

Highest Common Factor of 477,365,474 using Euclid's algorithm

Highest Common Factor of 477,365,474 is 1

Step 1: Since 477 > 365, we apply the division lemma to 477 and 365, to get

477 = 365 x 1 + 112

Step 2: Since the reminder 365 ≠ 0, we apply division lemma to 112 and 365, to get

365 = 112 x 3 + 29

Step 3: We consider the new divisor 112 and the new remainder 29, and apply the division lemma to get

112 = 29 x 3 + 25

We consider the new divisor 29 and the new remainder 25,and apply the division lemma to get

29 = 25 x 1 + 4

We consider the new divisor 25 and the new remainder 4,and apply the division lemma to get

25 = 4 x 6 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 477 and 365 is 1

Notice that 1 = HCF(4,1) = HCF(25,4) = HCF(29,25) = HCF(112,29) = HCF(365,112) = HCF(477,365) .

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

Step 1: Since 474 > 1, we apply the division lemma to 474 and 1, to get

474 = 1 x 474 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 474 is 1

Notice that 1 = HCF(474,1) .
