HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 571, 943, 682, 523 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 571, 943, 682, 523 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 571, 943, 682, 523 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 571, 943, 682, 523 is 1.
HCF(571, 943, 682, 523) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 571, 943, 682, 523 is 1.
Step 1: Since 943 > 571, we apply the division lemma to 943 and 571, to get
943 = 571 x 1 + 372
Step 2: Since the reminder 571 ≠ 0, we apply division lemma to 372 and 571, to get
571 = 372 x 1 + 199
Step 3: We consider the new divisor 372 and the new remainder 199, and apply the division lemma to get
372 = 199 x 1 + 173
We consider the new divisor 199 and the new remainder 173,and apply the division lemma to get
199 = 173 x 1 + 26
We consider the new divisor 173 and the new remainder 26,and apply the division lemma to get
173 = 26 x 6 + 17
We consider the new divisor 26 and the new remainder 17,and apply the division lemma to get
26 = 17 x 1 + 9
We consider the new divisor 17 and the new remainder 9,and apply the division lemma to get
17 = 9 x 1 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 571 and 943 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(17,9) = HCF(26,17) = HCF(173,26) = HCF(199,173) = HCF(372,199) = HCF(571,372) = HCF(943,571) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 682 > 1, we apply the division lemma to 682 and 1, to get
682 = 1 x 682 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 682 is 1
Notice that 1 = HCF(682,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 523 > 1, we apply the division lemma to 523 and 1, to get
523 = 1 x 523 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 523 is 1
Notice that 1 = HCF(523,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
