HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1891, 151 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1891, 151 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 1891, 151 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 1891, 151 is 1.
HCF(1891, 151) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1891, 151 is 1.
Step 1: Since 1891 > 151, we apply the division lemma to 1891 and 151, to get
1891 = 151 x 12 + 79
Step 2: Since the reminder 151 ≠ 0, we apply division lemma to 79 and 151, to get
151 = 79 x 1 + 72
Step 3: We consider the new divisor 79 and the new remainder 72, and apply the division lemma to get
79 = 72 x 1 + 7
We consider the new divisor 72 and the new remainder 7,and apply the division lemma to get
72 = 7 x 10 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1891 and 151 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(72,7) = HCF(79,72) = HCF(151,79) = HCF(1891,151) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
Answer: Euclid's Division Algorithm is a technique to compute the Highest Common Factor (HCF) of given positive integers.
2. what is the HCF of 1891, 151?
Answer: HCF of 1891, 151 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 1891, 151 using Euclid's Algorithm?
Answer: For arbitrary numbers 1891, 151 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
