HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 238, 648, 288, 288 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 238, 648, 288, 288 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 238, 648, 288, 288 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 238, 648, 288, 288 is 2.
HCF(238, 648, 288, 288) = 2
HCF of 238, 648, 288, 288 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 238, 648, 288, 288 is 2.
Highest Common Factor of 238,648,288,288 is 2
Step 1: Since 648 > 238, we apply the division lemma to 648 and 238, to get
648 = 238 x 2 + 172
Step 2: Since the reminder 238 ≠ 0, we apply division lemma to 172 and 238, to get
238 = 172 x 1 + 66
Step 3: We consider the new divisor 172 and the new remainder 66, and apply the division lemma to get
172 = 66 x 2 + 40
We consider the new divisor 66 and the new remainder 40,and apply the division lemma to get
66 = 40 x 1 + 26
We consider the new divisor 40 and the new remainder 26,and apply the division lemma to get
40 = 26 x 1 + 14
We consider the new divisor 26 and the new remainder 14,and apply the division lemma to get
26 = 14 x 1 + 12
We consider the new divisor 14 and the new remainder 12,and apply the division lemma to get
14 = 12 x 1 + 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 238 and 648 is 2
Notice that 2 = HCF(12,2) = HCF(14,12) = HCF(26,14) = HCF(40,26) = HCF(66,40) = HCF(172,66) = HCF(238,172) = HCF(648,238) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 288 > 2, we apply the division lemma to 288 and 2, to get
288 = 2 x 144 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 288 is 2
Notice that 2 = HCF(288,2) .
