HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 472, 803, 312 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 472, 803, 312 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 472, 803, 312 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 472, 803, 312 is 1.

HCF(472, 803, 312) = 1

Highest Common Factor of 472,803,312 using Euclid's algorithm

Highest Common Factor of 472,803,312 is 1

Step 1: Since 803 > 472, we apply the division lemma to 803 and 472, to get

803 = 472 x 1 + 331

Step 2: Since the reminder 472 ≠ 0, we apply division lemma to 331 and 472, to get

472 = 331 x 1 + 141

Step 3: We consider the new divisor 331 and the new remainder 141, and apply the division lemma to get

331 = 141 x 2 + 49

We consider the new divisor 141 and the new remainder 49,and apply the division lemma to get

141 = 49 x 2 + 43

We consider the new divisor 49 and the new remainder 43,and apply the division lemma to get

49 = 43 x 1 + 6

We consider the new divisor 43 and the new remainder 6,and apply the division lemma to get

43 = 6 x 7 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 472 and 803 is 1

Notice that 1 = HCF(6,1) = HCF(43,6) = HCF(49,43) = HCF(141,49) = HCF(331,141) = HCF(472,331) = HCF(803,472) .

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

Step 1: Since 312 > 1, we apply the division lemma to 312 and 1, to get

312 = 1 x 312 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 312 is 1

Notice that 1 = HCF(312,1) .
