HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 684, 576, 843 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 684, 576, 843 is 3 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 684, 576, 843 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 684, 576, 843 is 3.
HCF(684, 576, 843) = 3
HCF of 684, 576, 843 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 684, 576, 843 is 3.
Highest Common Factor of 684,576,843 is 3
Step 1: Since 684 > 576, we apply the division lemma to 684 and 576, to get
684 = 576 x 1 + 108
Step 2: Since the reminder 576 ≠ 0, we apply division lemma to 108 and 576, to get
576 = 108 x 5 + 36
Step 3: We consider the new divisor 108 and the new remainder 36, and apply the division lemma to get
108 = 36 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 36, the HCF of 684 and 576 is 36
Notice that 36 = HCF(108,36) = HCF(576,108) = HCF(684,576) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 843 > 36, we apply the division lemma to 843 and 36, to get
843 = 36 x 23 + 15
Step 2: Since the reminder 36 ≠ 0, we apply division lemma to 15 and 36, to get
36 = 15 x 2 + 6
Step 3: We consider the new divisor 15 and the new remainder 6, and apply the division lemma to get
15 = 6 x 2 + 3
We consider the new divisor 6 and the new remainder 3, and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 36 and 843 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(36,15) = HCF(843,36) .
