HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 749, 317, 657 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 749, 317, 657 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 749, 317, 657 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 749, 317, 657 is 1.
HCF(749, 317, 657) = 1
HCF of 749, 317, 657 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 749, 317, 657 is 1.
Highest Common Factor of 749,317,657 is 1
Step 1: Since 749 > 317, we apply the division lemma to 749 and 317, to get
749 = 317 x 2 + 115
Step 2: Since the reminder 317 ≠ 0, we apply division lemma to 115 and 317, to get
317 = 115 x 2 + 87
Step 3: We consider the new divisor 115 and the new remainder 87, and apply the division lemma to get
115 = 87 x 1 + 28
We consider the new divisor 87 and the new remainder 28,and apply the division lemma to get
87 = 28 x 3 + 3
We consider the new divisor 28 and the new remainder 3,and apply the division lemma to get
28 = 3 x 9 + 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 749 and 317 is 1
Notice that 1 = HCF(3,1) = HCF(28,3) = HCF(87,28) = HCF(115,87) = HCF(317,115) = HCF(749,317) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 657 > 1, we apply the division lemma to 657 and 1, to get
657 = 1 x 657 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 657 is 1
Notice that 1 = HCF(657,1) .
