HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 432, 982, 435 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 432, 982, 435 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, 982, 435 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, 982, 435 is 1.
HCF(432, 982, 435) = 1
HCF of 432, 982, 435 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, 982, 435 is 1.
Highest Common Factor of 432,982,435 is 1
Step 1: Since 982 > 432, we apply the division lemma to 982 and 432, to get
982 = 432 x 2 + 118
Step 2: Since the reminder 432 ≠ 0, we apply division lemma to 118 and 432, to get
432 = 118 x 3 + 78
Step 3: We consider the new divisor 118 and the new remainder 78, and apply the division lemma to get
118 = 78 x 1 + 40
We consider the new divisor 78 and the new remainder 40,and apply the division lemma to get
78 = 40 x 1 + 38
We consider the new divisor 40 and the new remainder 38,and apply the division lemma to get
40 = 38 x 1 + 2
We consider the new divisor 38 and the new remainder 2,and apply the division lemma to get
38 = 2 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 432 and 982 is 2
Notice that 2 = HCF(38,2) = HCF(40,38) = HCF(78,40) = HCF(118,78) = HCF(432,118) = HCF(982,432) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 435 > 2, we apply the division lemma to 435 and 2, to get
435 = 2 x 217 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 435 is 1
Notice that 1 = HCF(2,1) = HCF(435,2) .
