HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 432, 89691 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 432, 89691 is 3 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, 89691 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, 89691 is 3.
HCF(432, 89691) = 3
HCF of 432, 89691 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, 89691 is 3.
Highest Common Factor of 432,89691 is 3
Step 1: Since 89691 > 432, we apply the division lemma to 89691 and 432, to get
89691 = 432 x 207 + 267
Step 2: Since the reminder 432 ≠ 0, we apply division lemma to 267 and 432, to get
432 = 267 x 1 + 165
Step 3: We consider the new divisor 267 and the new remainder 165, and apply the division lemma to get
267 = 165 x 1 + 102
We consider the new divisor 165 and the new remainder 102,and apply the division lemma to get
165 = 102 x 1 + 63
We consider the new divisor 102 and the new remainder 63,and apply the division lemma to get
102 = 63 x 1 + 39
We consider the new divisor 63 and the new remainder 39,and apply the division lemma to get
63 = 39 x 1 + 24
We consider the new divisor 39 and the new remainder 24,and apply the division lemma to get
39 = 24 x 1 + 15
We consider the new divisor 24 and the new remainder 15,and apply the division lemma to get
24 = 15 x 1 + 9
We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get
15 = 9 x 1 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 432 and 89691 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(24,15) = HCF(39,24) = HCF(63,39) = HCF(102,63) = HCF(165,102) = HCF(267,165) = HCF(432,267) = HCF(89691,432) .
