HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 288, 170, 864, 392 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 288, 170, 864, 392 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 288, 170, 864, 392 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 288, 170, 864, 392 is 2.
HCF(288, 170, 864, 392) = 2
HCF of 288, 170, 864, 392 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 288, 170, 864, 392 is 2.
Highest Common Factor of 288,170,864,392 is 2
Step 1: Since 288 > 170, we apply the division lemma to 288 and 170, to get
288 = 170 x 1 + 118
Step 2: Since the reminder 170 ≠ 0, we apply division lemma to 118 and 170, to get
170 = 118 x 1 + 52
Step 3: We consider the new divisor 118 and the new remainder 52, and apply the division lemma to get
118 = 52 x 2 + 14
We consider the new divisor 52 and the new remainder 14,and apply the division lemma to get
52 = 14 x 3 + 10
We consider the new divisor 14 and the new remainder 10,and apply the division lemma to get
14 = 10 x 1 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma 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 288 and 170 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(14,10) = HCF(52,14) = HCF(118,52) = HCF(170,118) = HCF(288,170) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 864 > 2, we apply the division lemma to 864 and 2, to get
864 = 2 x 432 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 864 is 2
Notice that 2 = HCF(864,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 392 > 2, we apply the division lemma to 392 and 2, to get
392 = 2 x 196 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 392 is 2
Notice that 2 = HCF(392,2) .
