HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 315, 747 i.e. 9 the largest integer that leaves a remainder zero for all numbers.
HCF of 315, 747 is 9 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 315, 747 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 315, 747 is 9.
HCF(315, 747) = 9
HCF of 315, 747 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 315, 747 is 9.
Highest Common Factor of 315,747 is 9
Step 1: Since 747 > 315, we apply the division lemma to 747 and 315, to get
747 = 315 x 2 + 117
Step 2: Since the reminder 315 ≠ 0, we apply division lemma to 117 and 315, to get
315 = 117 x 2 + 81
Step 3: We consider the new divisor 117 and the new remainder 81, and apply the division lemma to get
117 = 81 x 1 + 36
We consider the new divisor 81 and the new remainder 36,and apply the division lemma to get
81 = 36 x 2 + 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 315 and 747 is 9
Notice that 9 = HCF(36,9) = HCF(81,36) = HCF(117,81) = HCF(315,117) = HCF(747,315) .
