HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1215, 732 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 1215, 732 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 1215, 732 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 1215, 732 is 3.
HCF(1215, 732) = 3
HCF of 1215, 732 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1215, 732 is 3.
Highest Common Factor of 1215,732 is 3
Step 1: Since 1215 > 732, we apply the division lemma to 1215 and 732, to get
1215 = 732 x 1 + 483
Step 2: Since the reminder 732 ≠ 0, we apply division lemma to 483 and 732, to get
732 = 483 x 1 + 249
Step 3: We consider the new divisor 483 and the new remainder 249, and apply the division lemma to get
483 = 249 x 1 + 234
We consider the new divisor 249 and the new remainder 234,and apply the division lemma to get
249 = 234 x 1 + 15
We consider the new divisor 234 and the new remainder 15,and apply the division lemma to get
234 = 15 x 15 + 9
We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get
15 = 9 x 1 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 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 1215 and 732 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(234,15) = HCF(249,234) = HCF(483,249) = HCF(732,483) = HCF(1215,732) .
