HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 89, 338, 145 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 89, 338, 145 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 89, 338, 145 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 89, 338, 145 is 1.
HCF(89, 338, 145) = 1
HCF of 89, 338, 145 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 89, 338, 145 is 1.
Highest Common Factor of 89,338,145 is 1
Step 1: Since 338 > 89, we apply the division lemma to 338 and 89, to get
338 = 89 x 3 + 71
Step 2: Since the reminder 89 ≠ 0, we apply division lemma to 71 and 89, to get
89 = 71 x 1 + 18
Step 3: We consider the new divisor 71 and the new remainder 18, and apply the division lemma to get
71 = 18 x 3 + 17
We consider the new divisor 18 and the new remainder 17,and apply the division lemma to get
18 = 17 x 1 + 1
We consider the new divisor 17 and the new remainder 1,and apply the division lemma to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 89 and 338 is 1
Notice that 1 = HCF(17,1) = HCF(18,17) = HCF(71,18) = HCF(89,71) = HCF(338,89) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 145 > 1, we apply the division lemma to 145 and 1, to get
145 = 1 x 145 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 145 is 1
Notice that 1 = HCF(145,1) .
