HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 268, 145 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 268, 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 268, 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 268, 145 is 1.
HCF(268, 145) = 1
HCF of 268, 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 268, 145 is 1.
Highest Common Factor of 268,145 is 1
Step 1: Since 268 > 145, we apply the division lemma to 268 and 145, to get
268 = 145 x 1 + 123
Step 2: Since the reminder 145 ≠ 0, we apply division lemma to 123 and 145, to get
145 = 123 x 1 + 22
Step 3: We consider the new divisor 123 and the new remainder 22, and apply the division lemma to get
123 = 22 x 5 + 13
We consider the new divisor 22 and the new remainder 13,and apply the division lemma to get
22 = 13 x 1 + 9
We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get
13 = 9 x 1 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 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 268 and 145 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(22,13) = HCF(123,22) = HCF(145,123) = HCF(268,145) .
