HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1861, 5654 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1861, 5654 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 1861, 5654 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 1861, 5654 is 1.
HCF(1861, 5654) = 1
HCF of 1861, 5654 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1861, 5654 is 1.
Highest Common Factor of 1861,5654 is 1
Step 1: Since 5654 > 1861, we apply the division lemma to 5654 and 1861, to get
5654 = 1861 x 3 + 71
Step 2: Since the reminder 1861 ≠ 0, we apply division lemma to 71 and 1861, to get
1861 = 71 x 26 + 15
Step 3: We consider the new divisor 71 and the new remainder 15, and apply the division lemma to get
71 = 15 x 4 + 11
We consider the new divisor 15 and the new remainder 11,and apply the division lemma to get
15 = 11 x 1 + 4
We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get
11 = 4 x 2 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1861 and 5654 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(15,11) = HCF(71,15) = HCF(1861,71) = HCF(5654,1861) .
