HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 145, 989, 89 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 145, 989, 89 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 145, 989, 89 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 145, 989, 89 is 1.
HCF(145, 989, 89) = 1
HCF of 145, 989, 89 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 145, 989, 89 is 1.
Highest Common Factor of 145,989,89 is 1
Step 1: Since 989 > 145, we apply the division lemma to 989 and 145, to get
989 = 145 x 6 + 119
Step 2: Since the reminder 145 ≠ 0, we apply division lemma to 119 and 145, to get
145 = 119 x 1 + 26
Step 3: We consider the new divisor 119 and the new remainder 26, and apply the division lemma to get
119 = 26 x 4 + 15
We consider the new divisor 26 and the new remainder 15,and apply the division lemma to get
26 = 15 x 1 + 11
We consider the new divisor 15 and the new remainder 11,and apply the division lemma to get
15 = 11 x 1 + 4
We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get
11 = 4 x 2 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 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 145 and 989 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(15,11) = HCF(26,15) = HCF(119,26) = HCF(145,119) = HCF(989,145) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 89 > 1, we apply the division lemma to 89 and 1, to get
89 = 1 x 89 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 89 is 1
Notice that 1 = HCF(89,1) .
