HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 507, 2981 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 507, 2981 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 507, 2981 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, 2981 is 1.
HCF(507, 2981) = 1
HCF of 507, 2981 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, 2981 is 1.
Highest Common Factor of 507,2981 is 1
Step 1: Since 2981 > 507, we apply the division lemma to 2981 and 507, to get
2981 = 507 x 5 + 446
Step 2: Since the reminder 507 ≠ 0, we apply division lemma to 446 and 507, to get
507 = 446 x 1 + 61
Step 3: We consider the new divisor 446 and the new remainder 61, and apply the division lemma to get
446 = 61 x 7 + 19
We consider the new divisor 61 and the new remainder 19,and apply the division lemma to get
61 = 19 x 3 + 4
We consider the new divisor 19 and the new remainder 4,and apply the division lemma to get
19 = 4 x 4 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 507 and 2981 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(19,4) = HCF(61,19) = HCF(446,61) = HCF(507,446) = HCF(2981,507) .
