HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 457, 733 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 457, 733 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 457, 733 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 457, 733 is 1.

HCF(457, 733) = 1

Highest common factor (HCF) of 457, 733 is 1.

Highest Common Factor of 457,733 using Euclid's algorithm

Highest Common Factor of 457,733 is 1

Step 1: Since 733 > 457, we apply the division lemma to 733 and 457, to get

733 = 457 x 1 + 276

Step 2: Since the reminder 457 ≠ 0, we apply division lemma to 276 and 457, to get

457 = 276 x 1 + 181

Step 3: We consider the new divisor 276 and the new remainder 181, and apply the division lemma to get

276 = 181 x 1 + 95

We consider the new divisor 181 and the new remainder 95,and apply the division lemma to get

181 = 95 x 1 + 86

We consider the new divisor 95 and the new remainder 86,and apply the division lemma to get

95 = 86 x 1 + 9

We consider the new divisor 86 and the new remainder 9,and apply the division lemma to get

86 = 9 x 9 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 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 457 and 733 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(86,9) = HCF(95,86) = HCF(181,95) = HCF(276,181) = HCF(457,276) = HCF(733,457) .
