HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 99, 47, 565, 809 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 99, 47, 565, 809 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 99, 47, 565, 809 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 99, 47, 565, 809 is 1.
HCF(99, 47, 565, 809) = 1
HCF of 99, 47, 565, 809 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 99, 47, 565, 809 is 1.
Highest Common Factor of 99,47,565,809 is 1
Step 1: Since 99 > 47, we apply the division lemma to 99 and 47, to get
99 = 47 x 2 + 5
Step 2: Since the reminder 47 ≠ 0, we apply division lemma to 5 and 47, to get
47 = 5 x 9 + 2
Step 3: We consider the new divisor 5 and the new remainder 2, and apply the division lemma to get
5 = 2 x 2 + 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 99 and 47 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(47,5) = HCF(99,47) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 565 > 1, we apply the division lemma to 565 and 1, to get
565 = 1 x 565 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 565 is 1
Notice that 1 = HCF(565,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 809 > 1, we apply the division lemma to 809 and 1, to get
809 = 1 x 809 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 809 is 1
Notice that 1 = HCF(809,1) .
