HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 387, 246, 717 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 387, 246, 717 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 387, 246, 717 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 387, 246, 717 is 3.
HCF(387, 246, 717) = 3
HCF of 387, 246, 717 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 387, 246, 717 is 3.
Highest Common Factor of 387,246,717 is 3
Step 1: Since 387 > 246, we apply the division lemma to 387 and 246, to get
387 = 246 x 1 + 141
Step 2: Since the reminder 246 ≠ 0, we apply division lemma to 141 and 246, to get
246 = 141 x 1 + 105
Step 3: We consider the new divisor 141 and the new remainder 105, and apply the division lemma to get
141 = 105 x 1 + 36
We consider the new divisor 105 and the new remainder 36,and apply the division lemma to get
105 = 36 x 2 + 33
We consider the new divisor 36 and the new remainder 33,and apply the division lemma to get
36 = 33 x 1 + 3
We consider the new divisor 33 and the new remainder 3,and apply the division lemma to get
33 = 3 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 387 and 246 is 3
Notice that 3 = HCF(33,3) = HCF(36,33) = HCF(105,36) = HCF(141,105) = HCF(246,141) = HCF(387,246) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 717 > 3, we apply the division lemma to 717 and 3, to get
717 = 3 x 239 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 717 is 3
Notice that 3 = HCF(717,3) .
