HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 28, 70, 316 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 28, 70, 316 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 28, 70, 316 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 28, 70, 316 is 2.
HCF(28, 70, 316) = 2
HCF of 28, 70, 316 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 28, 70, 316 is 2.
Highest Common Factor of 28,70,316 is 2
Step 1: Since 70 > 28, we apply the division lemma to 70 and 28, to get
70 = 28 x 2 + 14
Step 2: Since the reminder 28 ≠ 0, we apply division lemma to 14 and 28, to get
28 = 14 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 28 and 70 is 14
Notice that 14 = HCF(28,14) = HCF(70,28) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 316 > 14, we apply the division lemma to 316 and 14, to get
316 = 14 x 22 + 8
Step 2: Since the reminder 14 ≠ 0, we apply division lemma to 8 and 14, to get
14 = 8 x 1 + 6
Step 3: We consider the new divisor 8 and the new remainder 6, and apply the division lemma to get
8 = 6 x 1 + 2
We consider the new divisor 6 and the new remainder 2, and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 14 and 316 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(14,8) = HCF(316,14) .
