HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 717, 72740 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 717, 72740 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 717, 72740 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 717, 72740 is 1.
HCF(717, 72740) = 1
HCF of 717, 72740 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 717, 72740 is 1.
Highest Common Factor of 717,72740 is 1
Step 1: Since 72740 > 717, we apply the division lemma to 72740 and 717, to get
72740 = 717 x 101 + 323
Step 2: Since the reminder 717 ≠ 0, we apply division lemma to 323 and 717, to get
717 = 323 x 2 + 71
Step 3: We consider the new divisor 323 and the new remainder 71, and apply the division lemma to get
323 = 71 x 4 + 39
We consider the new divisor 71 and the new remainder 39,and apply the division lemma to get
71 = 39 x 1 + 32
We consider the new divisor 39 and the new remainder 32,and apply the division lemma to get
39 = 32 x 1 + 7
We consider the new divisor 32 and the new remainder 7,and apply the division lemma to get
32 = 7 x 4 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 717 and 72740 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(32,7) = HCF(39,32) = HCF(71,39) = HCF(323,71) = HCF(717,323) = HCF(72740,717) .
