HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 623, 862, 862 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 623, 862, 862 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 623, 862, 862 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 623, 862, 862 is 1.

HCF(623, 862, 862) = 1

Highest Common Factor of 623,862,862 using Euclid's algorithm

Highest Common Factor of 623,862,862 is 1

Step 1: Since 862 > 623, we apply the division lemma to 862 and 623, to get

862 = 623 x 1 + 239

Step 2: Since the reminder 623 ≠ 0, we apply division lemma to 239 and 623, to get

623 = 239 x 2 + 145

Step 3: We consider the new divisor 239 and the new remainder 145, and apply the division lemma to get

239 = 145 x 1 + 94

We consider the new divisor 145 and the new remainder 94,and apply the division lemma to get

145 = 94 x 1 + 51

We consider the new divisor 94 and the new remainder 51,and apply the division lemma to get

94 = 51 x 1 + 43

We consider the new divisor 51 and the new remainder 43,and apply the division lemma to get

51 = 43 x 1 + 8

We consider the new divisor 43 and the new remainder 8,and apply the division lemma to get

43 = 8 x 5 + 3

We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get

8 = 3 x 2 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 623 and 862 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(43,8) = HCF(51,43) = HCF(94,51) = HCF(145,94) = HCF(239,145) = HCF(623,239) = HCF(862,623) .

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

Step 1: Since 862 > 1, we apply the division lemma to 862 and 1, to get

862 = 1 x 862 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 862 is 1

Notice that 1 = HCF(862,1) .
