HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 613, 738, 18 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 613, 738, 18 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 613, 738, 18 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 613, 738, 18 is 1.
HCF(613, 738, 18) = 1
HCF of 613, 738, 18 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 613, 738, 18 is 1.
Highest Common Factor of 613,738,18 is 1
Step 1: Since 738 > 613, we apply the division lemma to 738 and 613, to get
738 = 613 x 1 + 125
Step 2: Since the reminder 613 ≠ 0, we apply division lemma to 125 and 613, to get
613 = 125 x 4 + 113
Step 3: We consider the new divisor 125 and the new remainder 113, and apply the division lemma to get
125 = 113 x 1 + 12
We consider the new divisor 113 and the new remainder 12,and apply the division lemma to get
113 = 12 x 9 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 613 and 738 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(113,12) = HCF(125,113) = HCF(613,125) = HCF(738,613) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 18 > 1, we apply the division lemma to 18 and 1, to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 18 is 1
Notice that 1 = HCF(18,1) .
