HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7439, 2163 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 7439, 2163 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 7439, 2163 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 7439, 2163 is 1.
HCF(7439, 2163) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7439, 2163 is 1.
Step 1: Since 7439 > 2163, we apply the division lemma to 7439 and 2163, to get
7439 = 2163 x 3 + 950
Step 2: Since the reminder 2163 ≠ 0, we apply division lemma to 950 and 2163, to get
2163 = 950 x 2 + 263
Step 3: We consider the new divisor 950 and the new remainder 263, and apply the division lemma to get
950 = 263 x 3 + 161
We consider the new divisor 263 and the new remainder 161,and apply the division lemma to get
263 = 161 x 1 + 102
We consider the new divisor 161 and the new remainder 102,and apply the division lemma to get
161 = 102 x 1 + 59
We consider the new divisor 102 and the new remainder 59,and apply the division lemma to get
102 = 59 x 1 + 43
We consider the new divisor 59 and the new remainder 43,and apply the division lemma to get
59 = 43 x 1 + 16
We consider the new divisor 43 and the new remainder 16,and apply the division lemma to get
43 = 16 x 2 + 11
We consider the new divisor 16 and the new remainder 11,and apply the division lemma to get
16 = 11 x 1 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7439 and 2163 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(16,11) = HCF(43,16) = HCF(59,43) = HCF(102,59) = HCF(161,102) = HCF(263,161) = HCF(950,263) = HCF(2163,950) = HCF(7439,2163) .
Here are some samples of HCF using Euclid's Algorithm calculations.
