HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 551, 437, 264 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 551, 437, 264 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 551, 437, 264 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 551, 437, 264 is 1.
HCF(551, 437, 264) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 551, 437, 264 is 1.
Step 1: Since 551 > 437, we apply the division lemma to 551 and 437, to get
551 = 437 x 1 + 114
Step 2: Since the reminder 437 ≠ 0, we apply division lemma to 114 and 437, to get
437 = 114 x 3 + 95
Step 3: We consider the new divisor 114 and the new remainder 95, and apply the division lemma to get
114 = 95 x 1 + 19
We consider the new divisor 95 and the new remainder 19, and apply the division lemma to get
95 = 19 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 551 and 437 is 19
Notice that 19 = HCF(95,19) = HCF(114,95) = HCF(437,114) = HCF(551,437) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 264 > 19, we apply the division lemma to 264 and 19, to get
264 = 19 x 13 + 17
Step 2: Since the reminder 19 ≠ 0, we apply division lemma to 17 and 19, to get
19 = 17 x 1 + 2
Step 3: We consider the new divisor 17 and the new remainder 2, and apply the division lemma to get
17 = 2 x 8 + 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 19 and 264 is 1
Notice that 1 = HCF(2,1) = HCF(17,2) = HCF(19,17) = HCF(264,19) .
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 551, 437, 264?
Answer: HCF of 551, 437, 264 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 551, 437, 264 using Euclid's Algorithm?
Answer: For arbitrary numbers 551, 437, 264 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
