HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 628, 713, 472 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 628, 713, 472 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 628, 713, 472 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 628, 713, 472 is 1.

HCF(628, 713, 472) = 1

Highest common factor (HCF) of 628, 713, 472 is 1.

Highest Common Factor of 628,713,472 using Euclid's algorithm

Highest Common Factor of 628,713,472 is 1

Step 1: Since 713 > 628, we apply the division lemma to 713 and 628, to get

713 = 628 x 1 + 85

Step 2: Since the reminder 628 ≠ 0, we apply division lemma to 85 and 628, to get

628 = 85 x 7 + 33

Step 3: We consider the new divisor 85 and the new remainder 33, and apply the division lemma to get

85 = 33 x 2 + 19

We consider the new divisor 33 and the new remainder 19,and apply the division lemma to get

33 = 19 x 1 + 14

We consider the new divisor 19 and the new remainder 14,and apply the division lemma to get

19 = 14 x 1 + 5

We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get

14 = 5 x 2 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 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 628 and 713 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(19,14) = HCF(33,19) = HCF(85,33) = HCF(628,85) = HCF(713,628) .

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

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

472 = 1 x 472 + 0

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

Notice that 1 = HCF(472,1) .
