HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 523, 2724, 8723 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 523, 2724, 8723 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 523, 2724, 8723 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 523, 2724, 8723 is 1.
HCF(523, 2724, 8723) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 523, 2724, 8723 is 1.
Step 1: Since 2724 > 523, we apply the division lemma to 2724 and 523, to get
2724 = 523 x 5 + 109
Step 2: Since the reminder 523 ≠ 0, we apply division lemma to 109 and 523, to get
523 = 109 x 4 + 87
Step 3: We consider the new divisor 109 and the new remainder 87, and apply the division lemma to get
109 = 87 x 1 + 22
We consider the new divisor 87 and the new remainder 22,and apply the division lemma to get
87 = 22 x 3 + 21
We consider the new divisor 22 and the new remainder 21,and apply the division lemma to get
22 = 21 x 1 + 1
We consider the new divisor 21 and the new remainder 1,and apply the division lemma to get
21 = 1 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 523 and 2724 is 1
Notice that 1 = HCF(21,1) = HCF(22,21) = HCF(87,22) = HCF(109,87) = HCF(523,109) = HCF(2724,523) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 8723 > 1, we apply the division lemma to 8723 and 1, to get
8723 = 1 x 8723 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 8723 is 1
Notice that 1 = HCF(8723,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
