HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1818, 2195 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1818, 2195 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 1818, 2195 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 1818, 2195 is 1.
HCF(1818, 2195) = 1
HCF of 1818, 2195 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1818, 2195 is 1.
Highest Common Factor of 1818,2195 is 1
Step 1: Since 2195 > 1818, we apply the division lemma to 2195 and 1818, to get
2195 = 1818 x 1 + 377
Step 2: Since the reminder 1818 ≠ 0, we apply division lemma to 377 and 1818, to get
1818 = 377 x 4 + 310
Step 3: We consider the new divisor 377 and the new remainder 310, and apply the division lemma to get
377 = 310 x 1 + 67
We consider the new divisor 310 and the new remainder 67,and apply the division lemma to get
310 = 67 x 4 + 42
We consider the new divisor 67 and the new remainder 42,and apply the division lemma to get
67 = 42 x 1 + 25
We consider the new divisor 42 and the new remainder 25,and apply the division lemma to get
42 = 25 x 1 + 17
We consider the new divisor 25 and the new remainder 17,and apply the division lemma to get
25 = 17 x 1 + 8
We consider the new divisor 17 and the new remainder 8,and apply the division lemma to get
17 = 8 x 2 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1818 and 2195 is 1
Notice that 1 = HCF(8,1) = HCF(17,8) = HCF(25,17) = HCF(42,25) = HCF(67,42) = HCF(310,67) = HCF(377,310) = HCF(1818,377) = HCF(2195,1818) .
