HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 511, 387 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 511, 387 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 511, 387 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 511, 387 is 1.
HCF(511, 387) = 1
HCF of 511, 387 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 511, 387 is 1.
Highest Common Factor of 511,387 is 1
Step 1: Since 511 > 387, we apply the division lemma to 511 and 387, to get
511 = 387 x 1 + 124
Step 2: Since the reminder 387 ≠ 0, we apply division lemma to 124 and 387, to get
387 = 124 x 3 + 15
Step 3: We consider the new divisor 124 and the new remainder 15, and apply the division lemma to get
124 = 15 x 8 + 4
We consider the new divisor 15 and the new remainder 4,and apply the division lemma to get
15 = 4 x 3 + 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 511 and 387 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(15,4) = HCF(124,15) = HCF(387,124) = HCF(511,387) .
