HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 423, 534, 315 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 423, 534, 315 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, 534, 315 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, 534, 315 is 3.
HCF(423, 534, 315) = 3
HCF of 423, 534, 315 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, 534, 315 is 3.
Highest Common Factor of 423,534,315 is 3
Step 1: Since 534 > 423, we apply the division lemma to 534 and 423, to get
534 = 423 x 1 + 111
Step 2: Since the reminder 423 ≠ 0, we apply division lemma to 111 and 423, to get
423 = 111 x 3 + 90
Step 3: We consider the new divisor 111 and the new remainder 90, and apply the division lemma to get
111 = 90 x 1 + 21
We consider the new divisor 90 and the new remainder 21,and apply the division lemma to get
90 = 21 x 4 + 6
We consider the new divisor 21 and the new remainder 6,and apply the division lemma to get
21 = 6 x 3 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 423 and 534 is 3
Notice that 3 = HCF(6,3) = HCF(21,6) = HCF(90,21) = HCF(111,90) = HCF(423,111) = HCF(534,423) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 315 > 3, we apply the division lemma to 315 and 3, to get
315 = 3 x 105 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 315 is 3
Notice that 3 = HCF(315,3) .
