HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 191, 507 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 191, 507 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 191, 507 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 191, 507 is 1.
HCF(191, 507) = 1
HCF of 191, 507 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 191, 507 is 1.
Highest Common Factor of 191,507 is 1
Step 1: Since 507 > 191, we apply the division lemma to 507 and 191, to get
507 = 191 x 2 + 125
Step 2: Since the reminder 191 ≠ 0, we apply division lemma to 125 and 191, to get
191 = 125 x 1 + 66
Step 3: We consider the new divisor 125 and the new remainder 66, and apply the division lemma to get
125 = 66 x 1 + 59
We consider the new divisor 66 and the new remainder 59,and apply the division lemma to get
66 = 59 x 1 + 7
We consider the new divisor 59 and the new remainder 7,and apply the division lemma to get
59 = 7 x 8 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 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 191 and 507 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(59,7) = HCF(66,59) = HCF(125,66) = HCF(191,125) = HCF(507,191) .
