HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 909, 569, 540 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 909, 569, 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 909, 569, 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 909, 569, 540 is 1.
HCF(909, 569, 540) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 909, 569, 540 is 1.
Step 1: Since 909 > 569, we apply the division lemma to 909 and 569, to get
909 = 569 x 1 + 340
Step 2: Since the reminder 569 ≠ 0, we apply division lemma to 340 and 569, to get
569 = 340 x 1 + 229
Step 3: We consider the new divisor 340 and the new remainder 229, and apply the division lemma to get
340 = 229 x 1 + 111
We consider the new divisor 229 and the new remainder 111,and apply the division lemma to get
229 = 111 x 2 + 7
We consider the new divisor 111 and the new remainder 7,and apply the division lemma to get
111 = 7 x 15 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 909 and 569 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(111,7) = HCF(229,111) = HCF(340,229) = HCF(569,340) = HCF(909,569) .
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) .
Here are some samples of HCF using Euclid's Algorithm calculations.
