HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 462, 858, 175 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 462, 858, 175 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 462, 858, 175 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 462, 858, 175 is 1.
HCF(462, 858, 175) = 1
HCF of 462, 858, 175 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 462, 858, 175 is 1.
Highest Common Factor of 462,858,175 is 1
Step 1: Since 858 > 462, we apply the division lemma to 858 and 462, to get
858 = 462 x 1 + 396
Step 2: Since the reminder 462 ≠ 0, we apply division lemma to 396 and 462, to get
462 = 396 x 1 + 66
Step 3: We consider the new divisor 396 and the new remainder 66, and apply the division lemma to get
396 = 66 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 66, the HCF of 462 and 858 is 66
Notice that 66 = HCF(396,66) = HCF(462,396) = HCF(858,462) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 175 > 66, we apply the division lemma to 175 and 66, to get
175 = 66 x 2 + 43
Step 2: Since the reminder 66 ≠ 0, we apply division lemma to 43 and 66, to get
66 = 43 x 1 + 23
Step 3: We consider the new divisor 43 and the new remainder 23, and apply the division lemma to get
43 = 23 x 1 + 20
We consider the new divisor 23 and the new remainder 20,and apply the division lemma to get
23 = 20 x 1 + 3
We consider the new divisor 20 and the new remainder 3,and apply the division lemma to get
20 = 3 x 6 + 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 66 and 175 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(20,3) = HCF(23,20) = HCF(43,23) = HCF(66,43) = HCF(175,66) .
