HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 751, 511 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 751, 511 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 751, 511 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 751, 511 is 1.
HCF(751, 511) = 1
HCF of 751, 511 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 751, 511 is 1.
Highest Common Factor of 751,511 is 1
Step 1: Since 751 > 511, we apply the division lemma to 751 and 511, to get
751 = 511 x 1 + 240
Step 2: Since the reminder 511 ≠ 0, we apply division lemma to 240 and 511, to get
511 = 240 x 2 + 31
Step 3: We consider the new divisor 240 and the new remainder 31, and apply the division lemma to get
240 = 31 x 7 + 23
We consider the new divisor 31 and the new remainder 23,and apply the division lemma to get
31 = 23 x 1 + 8
We consider the new divisor 23 and the new remainder 8,and apply the division lemma to get
23 = 8 x 2 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 751 and 511 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(23,8) = HCF(31,23) = HCF(240,31) = HCF(511,240) = HCF(751,511) .
