HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 180, 68151 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 180, 68151 is 3 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 180, 68151 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 180, 68151 is 3.
HCF(180, 68151) = 3
HCF of 180, 68151 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 180, 68151 is 3.
Highest Common Factor of 180,68151 is 3
Step 1: Since 68151 > 180, we apply the division lemma to 68151 and 180, to get
68151 = 180 x 378 + 111
Step 2: Since the reminder 180 ≠ 0, we apply division lemma to 111 and 180, to get
180 = 111 x 1 + 69
Step 3: We consider the new divisor 111 and the new remainder 69, and apply the division lemma to get
111 = 69 x 1 + 42
We consider the new divisor 69 and the new remainder 42,and apply the division lemma to get
69 = 42 x 1 + 27
We consider the new divisor 42 and the new remainder 27,and apply the division lemma to get
42 = 27 x 1 + 15
We consider the new divisor 27 and the new remainder 15,and apply the division lemma to get
27 = 15 x 1 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 180 and 68151 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(27,15) = HCF(42,27) = HCF(69,42) = HCF(111,69) = HCF(180,111) = HCF(68151,180) .
