HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 623, 142, 167 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 623, 142, 167 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, 142, 167 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, 142, 167 is 1.

HCF(623, 142, 167) = 1

Highest common factor (HCF) of 623, 142, 167 is 1.

Highest Common Factor of 623,142,167 using Euclid's algorithm

Highest Common Factor of 623,142,167 is 1

Step 1: Since 623 > 142, we apply the division lemma to 623 and 142, to get

623 = 142 x 4 + 55

Step 2: Since the reminder 142 ≠ 0, we apply division lemma to 55 and 142, to get

142 = 55 x 2 + 32

Step 3: We consider the new divisor 55 and the new remainder 32, and apply the division lemma to get

55 = 32 x 1 + 23

We consider the new divisor 32 and the new remainder 23,and apply the division lemma to get

32 = 23 x 1 + 9

We consider the new divisor 23 and the new remainder 9,and apply the division lemma to get

23 = 9 x 2 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 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 623 and 142 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(23,9) = HCF(32,23) = HCF(55,32) = HCF(142,55) = HCF(623,142) .

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

Step 1: Since 167 > 1, we apply the division lemma to 167 and 1, to get

167 = 1 x 167 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 167 is 1

Notice that 1 = HCF(167,1) .
