HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 486, 564 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 486, 564 is 6 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 486, 564 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 486, 564 is 6.
HCF(486, 564) = 6
HCF of 486, 564 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 486, 564 is 6.
Highest Common Factor of 486,564 is 6
Step 1: Since 564 > 486, we apply the division lemma to 564 and 486, to get
564 = 486 x 1 + 78
Step 2: Since the reminder 486 ≠ 0, we apply division lemma to 78 and 486, to get
486 = 78 x 6 + 18
Step 3: We consider the new divisor 78 and the new remainder 18, and apply the division lemma to get
78 = 18 x 4 + 6
We consider the new divisor 18 and the new remainder 6, and apply the division lemma to get
18 = 6 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 486 and 564 is 6
Notice that 6 = HCF(18,6) = HCF(78,18) = HCF(486,78) = HCF(564,486) .
