HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 717, 970 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 717, 970 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, 970 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, 970 is 1.
HCF(717, 970) = 1
HCF of 717, 970 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, 970 is 1.
Highest Common Factor of 717,970 is 1
Step 1: Since 970 > 717, we apply the division lemma to 970 and 717, to get
970 = 717 x 1 + 253
Step 2: Since the reminder 717 ≠ 0, we apply division lemma to 253 and 717, to get
717 = 253 x 2 + 211
Step 3: We consider the new divisor 253 and the new remainder 211, and apply the division lemma to get
253 = 211 x 1 + 42
We consider the new divisor 211 and the new remainder 42,and apply the division lemma to get
211 = 42 x 5 + 1
We consider the new divisor 42 and the new remainder 1,and apply the division lemma to get
42 = 1 x 42 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 717 and 970 is 1
Notice that 1 = HCF(42,1) = HCF(211,42) = HCF(253,211) = HCF(717,253) = HCF(970,717) .
