HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 5, 470, 218 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 5, 470, 218 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 5, 470, 218 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 5, 470, 218 is 1.
HCF(5, 470, 218) = 1
HCF of 5, 470, 218 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 5, 470, 218 is 1.
Highest Common Factor of 5,470,218 is 1
Step 1: Since 470 > 5, we apply the division lemma to 470 and 5, to get
470 = 5 x 94 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 470 is 5
Notice that 5 = HCF(470,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 218 > 5, we apply the division lemma to 218 and 5, to get
218 = 5 x 43 + 3
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get
5 = 3 x 1 + 2
Step 3: 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 5 and 218 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(218,5) .
