HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 321, 257, 784 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 321, 257, 784 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 321, 257, 784 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 321, 257, 784 is 1.
HCF(321, 257, 784) = 1
HCF of 321, 257, 784 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 321, 257, 784 is 1.
Highest Common Factor of 321,257,784 is 1
Step 1: Since 321 > 257, we apply the division lemma to 321 and 257, to get
321 = 257 x 1 + 64
Step 2: Since the reminder 257 ≠ 0, we apply division lemma to 64 and 257, to get
257 = 64 x 4 + 1
Step 3: We consider the new divisor 64 and the new remainder 1, and apply the division lemma to get
64 = 1 x 64 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 321 and 257 is 1
Notice that 1 = HCF(64,1) = HCF(257,64) = HCF(321,257) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 784 > 1, we apply the division lemma to 784 and 1, to get
784 = 1 x 784 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 784 is 1
Notice that 1 = HCF(784,1) .
