HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 284, 639, 439 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 284, 639, 439 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 284, 639, 439 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 284, 639, 439 is 1.
HCF(284, 639, 439) = 1
HCF of 284, 639, 439 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 284, 639, 439 is 1.
Highest Common Factor of 284,639,439 is 1
Step 1: Since 639 > 284, we apply the division lemma to 639 and 284, to get
639 = 284 x 2 + 71
Step 2: Since the reminder 284 ≠ 0, we apply division lemma to 71 and 284, to get
284 = 71 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 71, the HCF of 284 and 639 is 71
Notice that 71 = HCF(284,71) = HCF(639,284) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 439 > 71, we apply the division lemma to 439 and 71, to get
439 = 71 x 6 + 13
Step 2: Since the reminder 71 ≠ 0, we apply division lemma to 13 and 71, to get
71 = 13 x 5 + 6
Step 3: We consider the new divisor 13 and the new remainder 6, and apply the division lemma to get
13 = 6 x 2 + 1
We consider the new divisor 6 and the new remainder 1, and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 71 and 439 is 1
Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(71,13) = HCF(439,71) .
