HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 906, 645 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 906, 645 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 906, 645 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 906, 645 is 3.
HCF(906, 645) = 3
HCF of 906, 645 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 906, 645 is 3.
Highest Common Factor of 906,645 is 3
Step 1: Since 906 > 645, we apply the division lemma to 906 and 645, to get
906 = 645 x 1 + 261
Step 2: Since the reminder 645 ≠ 0, we apply division lemma to 261 and 645, to get
645 = 261 x 2 + 123
Step 3: We consider the new divisor 261 and the new remainder 123, and apply the division lemma to get
261 = 123 x 2 + 15
We consider the new divisor 123 and the new remainder 15,and apply the division lemma to get
123 = 15 x 8 + 3
We consider the new divisor 15 and the new remainder 3,and apply the division lemma to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 906 and 645 is 3
Notice that 3 = HCF(15,3) = HCF(123,15) = HCF(261,123) = HCF(645,261) = HCF(906,645) .
