HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 429, 544, 324 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 429, 544, 324 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 429, 544, 324 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 429, 544, 324 is 1.
HCF(429, 544, 324) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 429, 544, 324 is 1.
Step 1: Since 544 > 429, we apply the division lemma to 544 and 429, to get
544 = 429 x 1 + 115
Step 2: Since the reminder 429 ≠ 0, we apply division lemma to 115 and 429, to get
429 = 115 x 3 + 84
Step 3: We consider the new divisor 115 and the new remainder 84, and apply the division lemma to get
115 = 84 x 1 + 31
We consider the new divisor 84 and the new remainder 31,and apply the division lemma to get
84 = 31 x 2 + 22
We consider the new divisor 31 and the new remainder 22,and apply the division lemma to get
31 = 22 x 1 + 9
We consider the new divisor 22 and the new remainder 9,and apply the division lemma to get
22 = 9 x 2 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 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 429 and 544 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(22,9) = HCF(31,22) = HCF(84,31) = HCF(115,84) = HCF(429,115) = HCF(544,429) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 324 > 1, we apply the division lemma to 324 and 1, to get
324 = 1 x 324 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 324 is 1
Notice that 1 = HCF(324,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
