HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 731, 423, 612 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 731, 423, 612 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 731, 423, 612 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 731, 423, 612 is 1.

HCF(731, 423, 612) = 1

Highest common factor (HCF) of 731, 423, 612 is 1.

Highest Common Factor of 731,423,612 using Euclid's algorithm

Highest Common Factor of 731,423,612 is 1

Step 1: Since 731 > 423, we apply the division lemma to 731 and 423, to get

731 = 423 x 1 + 308

Step 2: Since the reminder 423 ≠ 0, we apply division lemma to 308 and 423, to get

423 = 308 x 1 + 115

Step 3: We consider the new divisor 308 and the new remainder 115, and apply the division lemma to get

308 = 115 x 2 + 78

We consider the new divisor 115 and the new remainder 78,and apply the division lemma to get

115 = 78 x 1 + 37

We consider the new divisor 78 and the new remainder 37,and apply the division lemma to get

78 = 37 x 2 + 4

We consider the new divisor 37 and the new remainder 4,and apply the division lemma to get

37 = 4 x 9 + 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 731 and 423 is 1

Notice that 1 = HCF(4,1) = HCF(37,4) = HCF(78,37) = HCF(115,78) = HCF(308,115) = HCF(423,308) = HCF(731,423) .

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

Step 1: Since 612 > 1, we apply the division lemma to 612 and 1, to get

612 = 1 x 612 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 612 is 1

Notice that 1 = HCF(612,1) .
