HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 517, 945 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 517, 945 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 517, 945 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 517, 945 is 1.
HCF(517, 945) = 1
HCF of 517, 945 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 517, 945 is 1.
Highest Common Factor of 517,945 is 1
Step 1: Since 945 > 517, we apply the division lemma to 945 and 517, to get
945 = 517 x 1 + 428
Step 2: Since the reminder 517 ≠ 0, we apply division lemma to 428 and 517, to get
517 = 428 x 1 + 89
Step 3: We consider the new divisor 428 and the new remainder 89, and apply the division lemma to get
428 = 89 x 4 + 72
We consider the new divisor 89 and the new remainder 72,and apply the division lemma to get
89 = 72 x 1 + 17
We consider the new divisor 72 and the new remainder 17,and apply the division lemma to get
72 = 17 x 4 + 4
We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get
17 = 4 x 4 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 517 and 945 is 1
Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(72,17) = HCF(89,72) = HCF(428,89) = HCF(517,428) = HCF(945,517) .
