HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1291, 5862, 65861 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1291, 5862, 65861 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 1291, 5862, 65861 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 1291, 5862, 65861 is 1.
HCF(1291, 5862, 65861) = 1
HCF of 1291, 5862, 65861 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1291, 5862, 65861 is 1.
Highest Common Factor of 1291,5862,65861 is 1
Step 1: Since 5862 > 1291, we apply the division lemma to 5862 and 1291, to get
5862 = 1291 x 4 + 698
Step 2: Since the reminder 1291 ≠ 0, we apply division lemma to 698 and 1291, to get
1291 = 698 x 1 + 593
Step 3: We consider the new divisor 698 and the new remainder 593, and apply the division lemma to get
698 = 593 x 1 + 105
We consider the new divisor 593 and the new remainder 105,and apply the division lemma to get
593 = 105 x 5 + 68
We consider the new divisor 105 and the new remainder 68,and apply the division lemma to get
105 = 68 x 1 + 37
We consider the new divisor 68 and the new remainder 37,and apply the division lemma to get
68 = 37 x 1 + 31
We consider the new divisor 37 and the new remainder 31,and apply the division lemma to get
37 = 31 x 1 + 6
We consider the new divisor 31 and the new remainder 6,and apply the division lemma to get
31 = 6 x 5 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1291 and 5862 is 1
Notice that 1 = HCF(6,1) = HCF(31,6) = HCF(37,31) = HCF(68,37) = HCF(105,68) = HCF(593,105) = HCF(698,593) = HCF(1291,698) = HCF(5862,1291) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 65861 > 1, we apply the division lemma to 65861 and 1, to get
65861 = 1 x 65861 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 65861 is 1
Notice that 1 = HCF(65861,1) .
