HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 155, 549, 880, 779 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 155, 549, 880, 779 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 155, 549, 880, 779 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 155, 549, 880, 779 is 1.
HCF(155, 549, 880, 779) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 155, 549, 880, 779 is 1.
Step 1: Since 549 > 155, we apply the division lemma to 549 and 155, to get
549 = 155 x 3 + 84
Step 2: Since the reminder 155 ≠ 0, we apply division lemma to 84 and 155, to get
155 = 84 x 1 + 71
Step 3: We consider the new divisor 84 and the new remainder 71, and apply the division lemma to get
84 = 71 x 1 + 13
We consider the new divisor 71 and the new remainder 13,and apply the division lemma to get
71 = 13 x 5 + 6
We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get
13 = 6 x 2 + 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 155 and 549 is 1
Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(71,13) = HCF(84,71) = HCF(155,84) = HCF(549,155) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 880 > 1, we apply the division lemma to 880 and 1, to get
880 = 1 x 880 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 880 is 1
Notice that 1 = HCF(880,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 779 > 1, we apply the division lemma to 779 and 1, to get
779 = 1 x 779 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 779 is 1
Notice that 1 = HCF(779,1) .
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 155, 549, 880, 779?
Answer: HCF of 155, 549, 880, 779 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 155, 549, 880, 779 using Euclid's Algorithm?
Answer: For arbitrary numbers 155, 549, 880, 779 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
