HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 423, 580, 863 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 423, 580, 863 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 423, 580, 863 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 423, 580, 863 is 1.

HCF(423, 580, 863) = 1

Highest common factor (HCF) of 423, 580, 863 is 1.

Highest Common Factor of 423,580,863 using Euclid's algorithm

Highest Common Factor of 423,580,863 is 1

Step 1: Since 580 > 423, we apply the division lemma to 580 and 423, to get

580 = 423 x 1 + 157

Step 2: Since the reminder 423 ≠ 0, we apply division lemma to 157 and 423, to get

423 = 157 x 2 + 109

Step 3: We consider the new divisor 157 and the new remainder 109, and apply the division lemma to get

157 = 109 x 1 + 48

We consider the new divisor 109 and the new remainder 48,and apply the division lemma to get

109 = 48 x 2 + 13

We consider the new divisor 48 and the new remainder 13,and apply the division lemma to get

48 = 13 x 3 + 9

We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get

13 = 9 x 1 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 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 423 and 580 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(48,13) = HCF(109,48) = HCF(157,109) = HCF(423,157) = HCF(580,423) .

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

Step 1: Since 863 > 1, we apply the division lemma to 863 and 1, to get

863 = 1 x 863 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 863 is 1

Notice that 1 = HCF(863,1) .
