HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 3645, 1858 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 3645, 1858 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 3645, 1858 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 3645, 1858 is 1.
HCF(3645, 1858) = 1
HCF of 3645, 1858 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 3645, 1858 is 1.
Highest Common Factor of 3645,1858 is 1
Step 1: Since 3645 > 1858, we apply the division lemma to 3645 and 1858, to get
3645 = 1858 x 1 + 1787
Step 2: Since the reminder 1858 ≠ 0, we apply division lemma to 1787 and 1858, to get
1858 = 1787 x 1 + 71
Step 3: We consider the new divisor 1787 and the new remainder 71, and apply the division lemma to get
1787 = 71 x 25 + 12
We consider the new divisor 71 and the new remainder 12,and apply the division lemma to get
71 = 12 x 5 + 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 3645 and 1858 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(71,12) = HCF(1787,71) = HCF(1858,1787) = HCF(3645,1858) .
