HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 472, 170, 347 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 472, 170, 347 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 472, 170, 347 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 472, 170, 347 is 1.
HCF(472, 170, 347) = 1
HCF of 472, 170, 347 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 472, 170, 347 is 1.
Highest Common Factor of 472,170,347 is 1
Step 1: Since 472 > 170, we apply the division lemma to 472 and 170, to get
472 = 170 x 2 + 132
Step 2: Since the reminder 170 ≠ 0, we apply division lemma to 132 and 170, to get
170 = 132 x 1 + 38
Step 3: We consider the new divisor 132 and the new remainder 38, and apply the division lemma to get
132 = 38 x 3 + 18
We consider the new divisor 38 and the new remainder 18,and apply the division lemma to get
38 = 18 x 2 + 2
We consider the new divisor 18 and the new remainder 2,and apply the division lemma to get
18 = 2 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 472 and 170 is 2
Notice that 2 = HCF(18,2) = HCF(38,18) = HCF(132,38) = HCF(170,132) = HCF(472,170) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 347 > 2, we apply the division lemma to 347 and 2, to get
347 = 2 x 173 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 347 is 1
Notice that 1 = HCF(2,1) = HCF(347,2) .
