HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 432, 287 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 432, 287 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, 287 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, 287 is 1.
HCF(432, 287) = 1
HCF of 432, 287 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 432, 287 is 1.
Highest Common Factor of 432,287 is 1
Step 1: Since 432 > 287, we apply the division lemma to 432 and 287, to get
432 = 287 x 1 + 145
Step 2: Since the reminder 287 ≠ 0, we apply division lemma to 145 and 287, to get
287 = 145 x 1 + 142
Step 3: We consider the new divisor 145 and the new remainder 142, and apply the division lemma to get
145 = 142 x 1 + 3
We consider the new divisor 142 and the new remainder 3,and apply the division lemma to get
142 = 3 x 47 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 432 and 287 is 1
Notice that 1 = HCF(3,1) = HCF(142,3) = HCF(145,142) = HCF(287,145) = HCF(432,287) .
