HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 247, 386, 315 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 247, 386, 315 is 1 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 247, 386, 315 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 247, 386, 315 is 1.
HCF(247, 386, 315) = 1
HCF of 247, 386, 315 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 247, 386, 315 is 1.
Highest Common Factor of 247,386,315 is 1
Step 1: Since 386 > 247, we apply the division lemma to 386 and 247, to get
386 = 247 x 1 + 139
Step 2: Since the reminder 247 ≠ 0, we apply division lemma to 139 and 247, to get
247 = 139 x 1 + 108
Step 3: We consider the new divisor 139 and the new remainder 108, and apply the division lemma to get
139 = 108 x 1 + 31
We consider the new divisor 108 and the new remainder 31,and apply the division lemma to get
108 = 31 x 3 + 15
We consider the new divisor 31 and the new remainder 15,and apply the division lemma to get
31 = 15 x 2 + 1
We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 247 and 386 is 1
Notice that 1 = HCF(15,1) = HCF(31,15) = HCF(108,31) = HCF(139,108) = HCF(247,139) = HCF(386,247) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 315 > 1, we apply the division lemma to 315 and 1, to get
315 = 1 x 315 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 315 is 1
Notice that 1 = HCF(315,1) .
