HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 561, 429, 481 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 561, 429, 481 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 561, 429, 481 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 561, 429, 481 is 1.
HCF(561, 429, 481) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 561, 429, 481 is 1.
Step 1: Since 561 > 429, we apply the division lemma to 561 and 429, to get
561 = 429 x 1 + 132
Step 2: Since the reminder 429 ≠ 0, we apply division lemma to 132 and 429, to get
429 = 132 x 3 + 33
Step 3: We consider the new divisor 132 and the new remainder 33, and apply the division lemma to get
132 = 33 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 33, the HCF of 561 and 429 is 33
Notice that 33 = HCF(132,33) = HCF(429,132) = HCF(561,429) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 481 > 33, we apply the division lemma to 481 and 33, to get
481 = 33 x 14 + 19
Step 2: Since the reminder 33 ≠ 0, we apply division lemma to 19 and 33, to get
33 = 19 x 1 + 14
Step 3: We consider the new divisor 19 and the new remainder 14, and apply the division lemma to get
19 = 14 x 1 + 5
We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get
14 = 5 x 2 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 33 and 481 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(19,14) = HCF(33,19) = HCF(481,33) .
Here are some samples of HCF using Euclid's Algorithm calculations.
