HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 837, 606, 485 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 837, 606, 485 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 837, 606, 485 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 837, 606, 485 is 1.
HCF(837, 606, 485) = 1
HCF of 837, 606, 485 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 837, 606, 485 is 1.
Highest Common Factor of 837,606,485 is 1
Step 1: Since 837 > 606, we apply the division lemma to 837 and 606, to get
837 = 606 x 1 + 231
Step 2: Since the reminder 606 ≠ 0, we apply division lemma to 231 and 606, to get
606 = 231 x 2 + 144
Step 3: We consider the new divisor 231 and the new remainder 144, and apply the division lemma to get
231 = 144 x 1 + 87
We consider the new divisor 144 and the new remainder 87,and apply the division lemma to get
144 = 87 x 1 + 57
We consider the new divisor 87 and the new remainder 57,and apply the division lemma to get
87 = 57 x 1 + 30
We consider the new divisor 57 and the new remainder 30,and apply the division lemma to get
57 = 30 x 1 + 27
We consider the new divisor 30 and the new remainder 27,and apply the division lemma to get
30 = 27 x 1 + 3
We consider the new divisor 27 and the new remainder 3,and apply the division lemma to get
27 = 3 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 837 and 606 is 3
Notice that 3 = HCF(27,3) = HCF(30,27) = HCF(57,30) = HCF(87,57) = HCF(144,87) = HCF(231,144) = HCF(606,231) = HCF(837,606) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 485 > 3, we apply the division lemma to 485 and 3, to get
485 = 3 x 161 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 485 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(485,3) .
