HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 462, 620, 486 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 462, 620, 486 is 2 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 462, 620, 486 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 462, 620, 486 is 2.
HCF(462, 620, 486) = 2
HCF of 462, 620, 486 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 462, 620, 486 is 2.
Highest Common Factor of 462,620,486 is 2
Step 1: Since 620 > 462, we apply the division lemma to 620 and 462, to get
620 = 462 x 1 + 158
Step 2: Since the reminder 462 ≠ 0, we apply division lemma to 158 and 462, to get
462 = 158 x 2 + 146
Step 3: We consider the new divisor 158 and the new remainder 146, and apply the division lemma to get
158 = 146 x 1 + 12
We consider the new divisor 146 and the new remainder 12,and apply the division lemma to get
146 = 12 x 12 + 2
We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get
12 = 2 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 462 and 620 is 2
Notice that 2 = HCF(12,2) = HCF(146,12) = HCF(158,146) = HCF(462,158) = HCF(620,462) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 486 > 2, we apply the division lemma to 486 and 2, to get
486 = 2 x 243 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 486 is 2
Notice that 2 = HCF(486,2) .
