HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 432, 755, 288 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 432, 755, 288 is 1 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 432, 755, 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 432, 755, 288 is 1.
HCF(432, 755, 288) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 432, 755, 288 is 1.
Step 1: Since 755 > 432, we apply the division lemma to 755 and 432, to get
755 = 432 x 1 + 323
Step 2: Since the reminder 432 ≠ 0, we apply division lemma to 323 and 432, to get
432 = 323 x 1 + 109
Step 3: We consider the new divisor 323 and the new remainder 109, and apply the division lemma to get
323 = 109 x 2 + 105
We consider the new divisor 109 and the new remainder 105,and apply the division lemma to get
109 = 105 x 1 + 4
We consider the new divisor 105 and the new remainder 4,and apply the division lemma to get
105 = 4 x 26 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 432 and 755 is 1
Notice that 1 = HCF(4,1) = HCF(105,4) = HCF(109,105) = HCF(323,109) = HCF(432,323) = HCF(755,432) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 288 > 1, we apply the division lemma to 288 and 1, to get
288 = 1 x 288 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 288 is 1
Notice that 1 = HCF(288,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
