HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 845, 556, 540 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 845, 556, 540 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 845, 556, 540 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 845, 556, 540 is 1.
HCF(845, 556, 540) = 1
HCF of 845, 556, 540 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 845, 556, 540 is 1.
Highest Common Factor of 845,556,540 is 1
Step 1: Since 845 > 556, we apply the division lemma to 845 and 556, to get
845 = 556 x 1 + 289
Step 2: Since the reminder 556 ≠ 0, we apply division lemma to 289 and 556, to get
556 = 289 x 1 + 267
Step 3: We consider the new divisor 289 and the new remainder 267, and apply the division lemma to get
289 = 267 x 1 + 22
We consider the new divisor 267 and the new remainder 22,and apply the division lemma to get
267 = 22 x 12 + 3
We consider the new divisor 22 and the new remainder 3,and apply the division lemma to get
22 = 3 x 7 + 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 845 and 556 is 1
Notice that 1 = HCF(3,1) = HCF(22,3) = HCF(267,22) = HCF(289,267) = HCF(556,289) = HCF(845,556) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 540 > 1, we apply the division lemma to 540 and 1, to get
540 = 1 x 540 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 540 is 1
Notice that 1 = HCF(540,1) .
