HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 782, 432 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 782, 432 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 782, 432 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 782, 432 is 2.
HCF(782, 432) = 2
HCF of 782, 432 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 782, 432 is 2.
Highest Common Factor of 782,432 is 2
Step 1: Since 782 > 432, we apply the division lemma to 782 and 432, to get
782 = 432 x 1 + 350
Step 2: Since the reminder 432 ≠ 0, we apply division lemma to 350 and 432, to get
432 = 350 x 1 + 82
Step 3: We consider the new divisor 350 and the new remainder 82, and apply the division lemma to get
350 = 82 x 4 + 22
We consider the new divisor 82 and the new remainder 22,and apply the division lemma to get
82 = 22 x 3 + 16
We consider the new divisor 22 and the new remainder 16,and apply the division lemma to get
22 = 16 x 1 + 6
We consider the new divisor 16 and the new remainder 6,and apply the division lemma to get
16 = 6 x 2 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 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 782 and 432 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(16,6) = HCF(22,16) = HCF(82,22) = HCF(350,82) = HCF(432,350) = HCF(782,432) .
