HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 318, 920, 408 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 318, 920, 408 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 318, 920, 408 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 318, 920, 408 is 2.
HCF(318, 920, 408) = 2
HCF of 318, 920, 408 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 318, 920, 408 is 2.
Highest Common Factor of 318,920,408 is 2
Step 1: Since 920 > 318, we apply the division lemma to 920 and 318, to get
920 = 318 x 2 + 284
Step 2: Since the reminder 318 ≠ 0, we apply division lemma to 284 and 318, to get
318 = 284 x 1 + 34
Step 3: We consider the new divisor 284 and the new remainder 34, and apply the division lemma to get
284 = 34 x 8 + 12
We consider the new divisor 34 and the new remainder 12,and apply the division lemma to get
34 = 12 x 2 + 10
We consider the new divisor 12 and the new remainder 10,and apply the division lemma to get
12 = 10 x 1 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 318 and 920 is 2
Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(34,12) = HCF(284,34) = HCF(318,284) = HCF(920,318) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 408 > 2, we apply the division lemma to 408 and 2, to get
408 = 2 x 204 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 408 is 2
Notice that 2 = HCF(408,2) .
