HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 440, 228, 288, 122 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 440, 228, 288, 122 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 440, 228, 288, 122 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 440, 228, 288, 122 is 2.
HCF(440, 228, 288, 122) = 2
HCF of 440, 228, 288, 122 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 440, 228, 288, 122 is 2.
Highest Common Factor of 440,228,288,122 is 2
Step 1: Since 440 > 228, we apply the division lemma to 440 and 228, to get
440 = 228 x 1 + 212
Step 2: Since the reminder 228 ≠ 0, we apply division lemma to 212 and 228, to get
228 = 212 x 1 + 16
Step 3: We consider the new divisor 212 and the new remainder 16, and apply the division lemma to get
212 = 16 x 13 + 4
We consider the new divisor 16 and the new remainder 4, and apply the division lemma to get
16 = 4 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 440 and 228 is 4
Notice that 4 = HCF(16,4) = HCF(212,16) = HCF(228,212) = HCF(440,228) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 288 > 4, we apply the division lemma to 288 and 4, to get
288 = 4 x 72 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 288 is 4
Notice that 4 = HCF(288,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 122 > 4, we apply the division lemma to 122 and 4, to get
122 = 4 x 30 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 122 is 2
Notice that 2 = HCF(4,2) = HCF(122,4) .
