HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 909, 4771, 7205 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 909, 4771, 7205 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, 4771, 7205 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, 4771, 7205 is 1.
HCF(909, 4771, 7205) = 1
HCF of 909, 4771, 7205 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 909, 4771, 7205 is 1.
Highest Common Factor of 909,4771,7205 is 1
Step 1: Since 4771 > 909, we apply the division lemma to 4771 and 909, to get
4771 = 909 x 5 + 226
Step 2: Since the reminder 909 ≠ 0, we apply division lemma to 226 and 909, to get
909 = 226 x 4 + 5
Step 3: We consider the new divisor 226 and the new remainder 5, and apply the division lemma to get
226 = 5 x 45 + 1
We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 909 and 4771 is 1
Notice that 1 = HCF(5,1) = HCF(226,5) = HCF(909,226) = HCF(4771,909) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 7205 > 1, we apply the division lemma to 7205 and 1, to get
7205 = 1 x 7205 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 7205 is 1
Notice that 1 = HCF(7205,1) .
