HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 441, 19936 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 441, 19936 is 7 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 441, 19936 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 441, 19936 is 7.
HCF(441, 19936) = 7
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 441, 19936 is 7.
Step 1: Since 19936 > 441, we apply the division lemma to 19936 and 441, to get
19936 = 441 x 45 + 91
Step 2: Since the reminder 441 ≠ 0, we apply division lemma to 91 and 441, to get
441 = 91 x 4 + 77
Step 3: We consider the new divisor 91 and the new remainder 77, and apply the division lemma to get
91 = 77 x 1 + 14
We consider the new divisor 77 and the new remainder 14,and apply the division lemma to get
77 = 14 x 5 + 7
We consider the new divisor 14 and the new remainder 7,and apply the division lemma to get
14 = 7 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 441 and 19936 is 7
Notice that 7 = HCF(14,7) = HCF(77,14) = HCF(91,77) = HCF(441,91) = HCF(19936,441) .
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 441, 19936?
Answer: HCF of 441, 19936 is 7 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 441, 19936 using Euclid's Algorithm?
Answer: For arbitrary numbers 441, 19936 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
