HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 284, 780, 399 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 284, 780, 399 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, 780, 399 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, 780, 399 is 1.
HCF(284, 780, 399) = 1
HCF of 284, 780, 399 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, 780, 399 is 1.
Highest Common Factor of 284,780,399 is 1
Step 1: Since 780 > 284, we apply the division lemma to 780 and 284, to get
780 = 284 x 2 + 212
Step 2: Since the reminder 284 ≠ 0, we apply division lemma to 212 and 284, to get
284 = 212 x 1 + 72
Step 3: We consider the new divisor 212 and the new remainder 72, and apply the division lemma to get
212 = 72 x 2 + 68
We consider the new divisor 72 and the new remainder 68,and apply the division lemma to get
72 = 68 x 1 + 4
We consider the new divisor 68 and the new remainder 4,and apply the division lemma to get
68 = 4 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 284 and 780 is 4
Notice that 4 = HCF(68,4) = HCF(72,68) = HCF(212,72) = HCF(284,212) = HCF(780,284) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 399 > 4, we apply the division lemma to 399 and 4, to get
399 = 4 x 99 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 399 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(399,4) .
