HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 459, 775, 148 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 459, 775, 148 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 459, 775, 148 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 459, 775, 148 is 1.

HCF(459, 775, 148) = 1

HCF of 459, 775, 148 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 459, 775, 148 is 1.

Highest Common Factor of 459,775,148 using Euclid's algorithm

Highest Common Factor of 459,775,148 is 1

Step 1: Since 775 > 459, we apply the division lemma to 775 and 459, to get

775 = 459 x 1 + 316

Step 2: Since the reminder 459 ≠ 0, we apply division lemma to 316 and 459, to get

459 = 316 x 1 + 143

Step 3: We consider the new divisor 316 and the new remainder 143, and apply the division lemma to get

316 = 143 x 2 + 30

We consider the new divisor 143 and the new remainder 30,and apply the division lemma to get

143 = 30 x 4 + 23

We consider the new divisor 30 and the new remainder 23,and apply the division lemma to get

30 = 23 x 1 + 7

We consider the new divisor 23 and the new remainder 7,and apply the division lemma to get

23 = 7 x 3 + 2

We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get

7 = 2 x 3 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 459 and 775 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(23,7) = HCF(30,23) = HCF(143,30) = HCF(316,143) = HCF(459,316) = HCF(775,459) .

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

Step 1: Since 148 > 1, we apply the division lemma to 148 and 1, to get

148 = 1 x 148 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 148 is 1

Notice that 1 = HCF(148,1) .
