HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 216, 308, 318 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 216, 308, 318 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 216, 308, 318 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 216, 308, 318 is 2.
HCF(216, 308, 318) = 2
HCF of 216, 308, 318 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 216, 308, 318 is 2.
Highest Common Factor of 216,308,318 is 2
Step 1: Since 308 > 216, we apply the division lemma to 308 and 216, to get
308 = 216 x 1 + 92
Step 2: Since the reminder 216 ≠ 0, we apply division lemma to 92 and 216, to get
216 = 92 x 2 + 32
Step 3: We consider the new divisor 92 and the new remainder 32, and apply the division lemma to get
92 = 32 x 2 + 28
We consider the new divisor 32 and the new remainder 28,and apply the division lemma to get
32 = 28 x 1 + 4
We consider the new divisor 28 and the new remainder 4,and apply the division lemma to get
28 = 4 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 216 and 308 is 4
Notice that 4 = HCF(28,4) = HCF(32,28) = HCF(92,32) = HCF(216,92) = HCF(308,216) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 318 > 4, we apply the division lemma to 318 and 4, to get
318 = 4 x 79 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 318 is 2
Notice that 2 = HCF(4,2) = HCF(318,4) .
