HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 511, 400, 425 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 511, 400, 425 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, 400, 425 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, 400, 425 is 1.
HCF(511, 400, 425) = 1
HCF of 511, 400, 425 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, 400, 425 is 1.
Highest Common Factor of 511,400,425 is 1
Step 1: Since 511 > 400, we apply the division lemma to 511 and 400, to get
511 = 400 x 1 + 111
Step 2: Since the reminder 400 ≠ 0, we apply division lemma to 111 and 400, to get
400 = 111 x 3 + 67
Step 3: We consider the new divisor 111 and the new remainder 67, and apply the division lemma to get
111 = 67 x 1 + 44
We consider the new divisor 67 and the new remainder 44,and apply the division lemma to get
67 = 44 x 1 + 23
We consider the new divisor 44 and the new remainder 23,and apply the division lemma to get
44 = 23 x 1 + 21
We consider the new divisor 23 and the new remainder 21,and apply the division lemma to get
23 = 21 x 1 + 2
We consider the new divisor 21 and the new remainder 2,and apply the division lemma to get
21 = 2 x 10 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 511 and 400 is 1
Notice that 1 = HCF(2,1) = HCF(21,2) = HCF(23,21) = HCF(44,23) = HCF(67,44) = HCF(111,67) = HCF(400,111) = HCF(511,400) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 425 > 1, we apply the division lemma to 425 and 1, to get
425 = 1 x 425 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 425 is 1
Notice that 1 = HCF(425,1) .
