HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 507, 345 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 507, 345 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 507, 345 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 507, 345 is 3.
HCF(507, 345) = 3
HCF of 507, 345 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 507, 345 is 3.
Highest Common Factor of 507,345 is 3
Step 1: Since 507 > 345, we apply the division lemma to 507 and 345, to get
507 = 345 x 1 + 162
Step 2: Since the reminder 345 ≠ 0, we apply division lemma to 162 and 345, to get
345 = 162 x 2 + 21
Step 3: We consider the new divisor 162 and the new remainder 21, and apply the division lemma to get
162 = 21 x 7 + 15
We consider the new divisor 21 and the new remainder 15,and apply the division lemma to get
21 = 15 x 1 + 6
We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get
15 = 6 x 2 + 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 507 and 345 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(21,15) = HCF(162,21) = HCF(345,162) = HCF(507,345) .
