HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 423, 264, 186 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 423, 264, 186 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 423, 264, 186 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 423, 264, 186 is 3.
HCF(423, 264, 186) = 3
HCF of 423, 264, 186 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 423, 264, 186 is 3.
Highest Common Factor of 423,264,186 is 3
Step 1: Since 423 > 264, we apply the division lemma to 423 and 264, to get
423 = 264 x 1 + 159
Step 2: Since the reminder 264 ≠ 0, we apply division lemma to 159 and 264, to get
264 = 159 x 1 + 105
Step 3: We consider the new divisor 159 and the new remainder 105, and apply the division lemma to get
159 = 105 x 1 + 54
We consider the new divisor 105 and the new remainder 54,and apply the division lemma to get
105 = 54 x 1 + 51
We consider the new divisor 54 and the new remainder 51,and apply the division lemma to get
54 = 51 x 1 + 3
We consider the new divisor 51 and the new remainder 3,and apply the division lemma to get
51 = 3 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 423 and 264 is 3
Notice that 3 = HCF(51,3) = HCF(54,51) = HCF(105,54) = HCF(159,105) = HCF(264,159) = HCF(423,264) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 186 > 3, we apply the division lemma to 186 and 3, to get
186 = 3 x 62 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 186 is 3
Notice that 3 = HCF(186,3) .
