HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 408, 652, 731 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 408, 652, 731 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 408, 652, 731 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 408, 652, 731 is 1.

HCF(408, 652, 731) = 1

Highest Common Factor of 408,652,731 using Euclid's algorithm

Highest Common Factor of 408,652,731 is 1

Step 1: Since 652 > 408, we apply the division lemma to 652 and 408, to get

652 = 408 x 1 + 244

Step 2: Since the reminder 408 ≠ 0, we apply division lemma to 244 and 408, to get

408 = 244 x 1 + 164

Step 3: We consider the new divisor 244 and the new remainder 164, and apply the division lemma to get

244 = 164 x 1 + 80

We consider the new divisor 164 and the new remainder 80,and apply the division lemma to get

164 = 80 x 2 + 4

We consider the new divisor 80 and the new remainder 4,and apply the division lemma to get

80 = 4 x 20 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 408 and 652 is 4

Notice that 4 = HCF(80,4) = HCF(164,80) = HCF(244,164) = HCF(408,244) = HCF(652,408) .

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

Step 1: Since 731 > 4, we apply the division lemma to 731 and 4, to get

731 = 4 x 182 + 3

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get

4 = 3 x 1 + 1

Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 731 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(731,4) .
