HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 440, 682, 288 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 440, 682, 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 440, 682, 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 440, 682, 288 is 2.
HCF(440, 682, 288) = 2
HCF of 440, 682, 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 440, 682, 288 is 2.
Highest Common Factor of 440,682,288 is 2
Step 1: Since 682 > 440, we apply the division lemma to 682 and 440, to get
682 = 440 x 1 + 242
Step 2: Since the reminder 440 ≠ 0, we apply division lemma to 242 and 440, to get
440 = 242 x 1 + 198
Step 3: We consider the new divisor 242 and the new remainder 198, and apply the division lemma to get
242 = 198 x 1 + 44
We consider the new divisor 198 and the new remainder 44,and apply the division lemma to get
198 = 44 x 4 + 22
We consider the new divisor 44 and the new remainder 22,and apply the division lemma to get
44 = 22 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 22, the HCF of 440 and 682 is 22
Notice that 22 = HCF(44,22) = HCF(198,44) = HCF(242,198) = HCF(440,242) = HCF(682,440) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 288 > 22, we apply the division lemma to 288 and 22, to get
288 = 22 x 13 + 2
Step 2: Since the reminder 22 ≠ 0, we apply division lemma to 2 and 22, to get
22 = 2 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 22 and 288 is 2
Notice that 2 = HCF(22,2) = HCF(288,22) .
