HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 713, 451 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 713, 451 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 713, 451 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 713, 451 is 1.

HCF(713, 451) = 1

Highest common factor (HCF) of 713, 451 is 1.

Highest Common Factor of 713,451 using Euclid's algorithm

Highest Common Factor of 713,451 is 1

Step 1: Since 713 > 451, we apply the division lemma to 713 and 451, to get

713 = 451 x 1 + 262

Step 2: Since the reminder 451 ≠ 0, we apply division lemma to 262 and 451, to get

451 = 262 x 1 + 189

Step 3: We consider the new divisor 262 and the new remainder 189, and apply the division lemma to get

262 = 189 x 1 + 73

We consider the new divisor 189 and the new remainder 73,and apply the division lemma to get

189 = 73 x 2 + 43

We consider the new divisor 73 and the new remainder 43,and apply the division lemma to get

73 = 43 x 1 + 30

We consider the new divisor 43 and the new remainder 30,and apply the division lemma to get

43 = 30 x 1 + 13

We consider the new divisor 30 and the new remainder 13,and apply the division lemma to get

30 = 13 x 2 + 4

We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get

13 = 4 x 3 + 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 713 and 451 is 1

Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(30,13) = HCF(43,30) = HCF(73,43) = HCF(189,73) = HCF(262,189) = HCF(451,262) = HCF(713,451) .
