HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 798, 1798, 3216 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 798, 1798, 3216 is 2 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 798, 1798, 3216 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 798, 1798, 3216 is 2.
HCF(798, 1798, 3216) = 2
HCF of 798, 1798, 3216 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 798, 1798, 3216 is 2.
Highest Common Factor of 798,1798,3216 is 2
Step 1: Since 1798 > 798, we apply the division lemma to 1798 and 798, to get
1798 = 798 x 2 + 202
Step 2: Since the reminder 798 ≠ 0, we apply division lemma to 202 and 798, to get
798 = 202 x 3 + 192
Step 3: We consider the new divisor 202 and the new remainder 192, and apply the division lemma to get
202 = 192 x 1 + 10
We consider the new divisor 192 and the new remainder 10,and apply the division lemma to get
192 = 10 x 19 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 798 and 1798 is 2
Notice that 2 = HCF(10,2) = HCF(192,10) = HCF(202,192) = HCF(798,202) = HCF(1798,798) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 3216 > 2, we apply the division lemma to 3216 and 2, to get
3216 = 2 x 1608 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 3216 is 2
Notice that 2 = HCF(3216,2) .
