HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 486, 864 i.e. 54 the largest integer that leaves a remainder zero for all numbers.
HCF of 486, 864 is 54 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, 864 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, 864 is 54.
HCF(486, 864) = 54
HCF of 486, 864 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, 864 is 54.
Highest Common Factor of 486,864 is 54
Step 1: Since 864 > 486, we apply the division lemma to 864 and 486, to get
864 = 486 x 1 + 378
Step 2: Since the reminder 486 ≠ 0, we apply division lemma to 378 and 486, to get
486 = 378 x 1 + 108
Step 3: We consider the new divisor 378 and the new remainder 108, and apply the division lemma to get
378 = 108 x 3 + 54
We consider the new divisor 108 and the new remainder 54, and apply the division lemma to get
108 = 54 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 54, the HCF of 486 and 864 is 54
Notice that 54 = HCF(108,54) = HCF(378,108) = HCF(486,378) = HCF(864,486) .
