HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 648, 444 i.e. 12 the largest integer that leaves a remainder zero for all numbers.
HCF of 648, 444 is 12 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 648, 444 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 648, 444 is 12.
HCF(648, 444) = 12
HCF of 648, 444 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 648, 444 is 12.
Highest Common Factor of 648,444 is 12
Step 1: Since 648 > 444, we apply the division lemma to 648 and 444, to get
648 = 444 x 1 + 204
Step 2: Since the reminder 444 ≠ 0, we apply division lemma to 204 and 444, to get
444 = 204 x 2 + 36
Step 3: We consider the new divisor 204 and the new remainder 36, and apply the division lemma to get
204 = 36 x 5 + 24
We consider the new divisor 36 and the new remainder 24,and apply the division lemma to get
36 = 24 x 1 + 12
We consider the new divisor 24 and the new remainder 12,and apply the division lemma to get
24 = 12 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 648 and 444 is 12
Notice that 12 = HCF(24,12) = HCF(36,24) = HCF(204,36) = HCF(444,204) = HCF(648,444) .
