HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 105, 717 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 105, 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 105, 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 105, 717 is 3.
HCF(105, 717) = 3
HCF of 105, 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 105, 717 is 3.
Highest Common Factor of 105,717 is 3
Step 1: Since 717 > 105, we apply the division lemma to 717 and 105, to get
717 = 105 x 6 + 87
Step 2: Since the reminder 105 ≠ 0, we apply division lemma to 87 and 105, to get
105 = 87 x 1 + 18
Step 3: We consider the new divisor 87 and the new remainder 18, and apply the division lemma to get
87 = 18 x 4 + 15
We consider the new divisor 18 and the new remainder 15,and apply the division lemma to get
18 = 15 x 1 + 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 105 and 717 is 3
Notice that 3 = HCF(15,3) = HCF(18,15) = HCF(87,18) = HCF(105,87) = HCF(717,105) .
