HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 511, 678, 69 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 511, 678, 69 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, 678, 69 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, 678, 69 is 1.
HCF(511, 678, 69) = 1
HCF of 511, 678, 69 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, 678, 69 is 1.
Highest Common Factor of 511,678,69 is 1
Step 1: Since 678 > 511, we apply the division lemma to 678 and 511, to get
678 = 511 x 1 + 167
Step 2: Since the reminder 511 ≠ 0, we apply division lemma to 167 and 511, to get
511 = 167 x 3 + 10
Step 3: We consider the new divisor 167 and the new remainder 10, and apply the division lemma to get
167 = 10 x 16 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 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 511 and 678 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(167,10) = HCF(511,167) = HCF(678,511) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 69 > 1, we apply the division lemma to 69 and 1, to get
69 = 1 x 69 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 69 is 1
Notice that 1 = HCF(69,1) .
