HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 216, 388, 210 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 216, 388, 210 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, 388, 210 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, 388, 210 is 2.
HCF(216, 388, 210) = 2
HCF of 216, 388, 210 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, 388, 210 is 2.
Highest Common Factor of 216,388,210 is 2
Step 1: Since 388 > 216, we apply the division lemma to 388 and 216, to get
388 = 216 x 1 + 172
Step 2: Since the reminder 216 ≠ 0, we apply division lemma to 172 and 216, to get
216 = 172 x 1 + 44
Step 3: We consider the new divisor 172 and the new remainder 44, and apply the division lemma to get
172 = 44 x 3 + 40
We consider the new divisor 44 and the new remainder 40,and apply the division lemma to get
44 = 40 x 1 + 4
We consider the new divisor 40 and the new remainder 4,and apply the division lemma to get
40 = 4 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 216 and 388 is 4
Notice that 4 = HCF(40,4) = HCF(44,40) = HCF(172,44) = HCF(216,172) = HCF(388,216) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 210 > 4, we apply the division lemma to 210 and 4, to get
210 = 4 x 52 + 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 210 is 2
Notice that 2 = HCF(4,2) = HCF(210,4) .
