HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 350, 3172, 1215 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 350, 3172, 1215 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 350, 3172, 1215 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 350, 3172, 1215 is 1.
HCF(350, 3172, 1215) = 1
HCF of 350, 3172, 1215 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 350, 3172, 1215 is 1.
Highest Common Factor of 350,3172,1215 is 1
Step 1: Since 3172 > 350, we apply the division lemma to 3172 and 350, to get
3172 = 350 x 9 + 22
Step 2: Since the reminder 350 ≠ 0, we apply division lemma to 22 and 350, to get
350 = 22 x 15 + 20
Step 3: We consider the new divisor 22 and the new remainder 20, and apply the division lemma to get
22 = 20 x 1 + 2
We consider the new divisor 20 and the new remainder 2, and apply the division lemma to get
20 = 2 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 350 and 3172 is 2
Notice that 2 = HCF(20,2) = HCF(22,20) = HCF(350,22) = HCF(3172,350) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 1215 > 2, we apply the division lemma to 1215 and 2, to get
1215 = 2 x 607 + 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 1215 is 1
Notice that 1 = HCF(2,1) = HCF(1215,2) .
