HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 784, 328 i.e. 8 the largest integer that leaves a remainder zero for all numbers.
HCF of 784, 328 is 8 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 784, 328 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 784, 328 is 8.
HCF(784, 328) = 8
HCF of 784, 328 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 784, 328 is 8.
Highest Common Factor of 784,328 is 8
Step 1: Since 784 > 328, we apply the division lemma to 784 and 328, to get
784 = 328 x 2 + 128
Step 2: Since the reminder 328 ≠ 0, we apply division lemma to 128 and 328, to get
328 = 128 x 2 + 72
Step 3: We consider the new divisor 128 and the new remainder 72, and apply the division lemma to get
128 = 72 x 1 + 56
We consider the new divisor 72 and the new remainder 56,and apply the division lemma to get
72 = 56 x 1 + 16
We consider the new divisor 56 and the new remainder 16,and apply the division lemma to get
56 = 16 x 3 + 8
We consider the new divisor 16 and the new remainder 8,and apply the division lemma to get
16 = 8 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 784 and 328 is 8
Notice that 8 = HCF(16,8) = HCF(56,16) = HCF(72,56) = HCF(128,72) = HCF(328,128) = HCF(784,328) .
