HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 900, 485, 811 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 900, 485, 811 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 900, 485, 811 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 900, 485, 811 is 1.
HCF(900, 485, 811) = 1
HCF of 900, 485, 811 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 900, 485, 811 is 1.
Highest Common Factor of 900,485,811 is 1
Step 1: Since 900 > 485, we apply the division lemma to 900 and 485, to get
900 = 485 x 1 + 415
Step 2: Since the reminder 485 ≠ 0, we apply division lemma to 415 and 485, to get
485 = 415 x 1 + 70
Step 3: We consider the new divisor 415 and the new remainder 70, and apply the division lemma to get
415 = 70 x 5 + 65
We consider the new divisor 70 and the new remainder 65,and apply the division lemma to get
70 = 65 x 1 + 5
We consider the new divisor 65 and the new remainder 5,and apply the division lemma to get
65 = 5 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 900 and 485 is 5
Notice that 5 = HCF(65,5) = HCF(70,65) = HCF(415,70) = HCF(485,415) = HCF(900,485) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 811 > 5, we apply the division lemma to 811 and 5, to get
811 = 5 x 162 + 1
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, 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 5 and 811 is 1
Notice that 1 = HCF(5,1) = HCF(811,5) .
