HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 729, 882, 24 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 729, 882, 24 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 729, 882, 24 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 729, 882, 24 is 3.
HCF(729, 882, 24) = 3
HCF of 729, 882, 24 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 729, 882, 24 is 3.
Highest Common Factor of 729,882,24 is 3
Step 1: Since 882 > 729, we apply the division lemma to 882 and 729, to get
882 = 729 x 1 + 153
Step 2: Since the reminder 729 ≠ 0, we apply division lemma to 153 and 729, to get
729 = 153 x 4 + 117
Step 3: We consider the new divisor 153 and the new remainder 117, and apply the division lemma to get
153 = 117 x 1 + 36
We consider the new divisor 117 and the new remainder 36,and apply the division lemma to get
117 = 36 x 3 + 9
We consider the new divisor 36 and the new remainder 9,and apply the division lemma to get
36 = 9 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 729 and 882 is 9
Notice that 9 = HCF(36,9) = HCF(117,36) = HCF(153,117) = HCF(729,153) = HCF(882,729) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 24 > 9, we apply the division lemma to 24 and 9, to get
24 = 9 x 2 + 6
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 6 and 9, to get
9 = 6 x 1 + 3
Step 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 9 and 24 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(24,9) .
