HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 658, 553, 354 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 658, 553, 354 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 658, 553, 354 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 658, 553, 354 is 1.
HCF(658, 553, 354) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 658, 553, 354 is 1.
Step 1: Since 658 > 553, we apply the division lemma to 658 and 553, to get
658 = 553 x 1 + 105
Step 2: Since the reminder 553 ≠ 0, we apply division lemma to 105 and 553, to get
553 = 105 x 5 + 28
Step 3: We consider the new divisor 105 and the new remainder 28, and apply the division lemma to get
105 = 28 x 3 + 21
We consider the new divisor 28 and the new remainder 21,and apply the division lemma to get
28 = 21 x 1 + 7
We consider the new divisor 21 and the new remainder 7,and apply the division lemma to get
21 = 7 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 658 and 553 is 7
Notice that 7 = HCF(21,7) = HCF(28,21) = HCF(105,28) = HCF(553,105) = HCF(658,553) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 354 > 7, we apply the division lemma to 354 and 7, to get
354 = 7 x 50 + 4
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 4 and 7, to get
7 = 4 x 1 + 3
Step 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 7 and 354 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(354,7) .
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 658, 553, 354?
Answer: HCF of 658, 553, 354 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 658, 553, 354 using Euclid's Algorithm?
Answer: For arbitrary numbers 658, 553, 354 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
