HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 622, 1467, 7898 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 622, 1467, 7898 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 622, 1467, 7898 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 622, 1467, 7898 is 1.
HCF(622, 1467, 7898) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 622, 1467, 7898 is 1.
Step 1: Since 1467 > 622, we apply the division lemma to 1467 and 622, to get
1467 = 622 x 2 + 223
Step 2: Since the reminder 622 ≠ 0, we apply division lemma to 223 and 622, to get
622 = 223 x 2 + 176
Step 3: We consider the new divisor 223 and the new remainder 176, and apply the division lemma to get
223 = 176 x 1 + 47
We consider the new divisor 176 and the new remainder 47,and apply the division lemma to get
176 = 47 x 3 + 35
We consider the new divisor 47 and the new remainder 35,and apply the division lemma to get
47 = 35 x 1 + 12
We consider the new divisor 35 and the new remainder 12,and apply the division lemma to get
35 = 12 x 2 + 11
We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 622 and 1467 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(35,12) = HCF(47,35) = HCF(176,47) = HCF(223,176) = HCF(622,223) = HCF(1467,622) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 7898 > 1, we apply the division lemma to 7898 and 1, to get
7898 = 1 x 7898 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 7898 is 1
Notice that 1 = HCF(7898,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
