HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 228, 872, 20 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 228, 872, 20 is 4 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 228, 872, 20 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 228, 872, 20 is 4.
HCF(228, 872, 20) = 4
HCF of 228, 872, 20 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 228, 872, 20 is 4.
Highest Common Factor of 228,872,20 is 4
Step 1: Since 872 > 228, we apply the division lemma to 872 and 228, to get
872 = 228 x 3 + 188
Step 2: Since the reminder 228 ≠ 0, we apply division lemma to 188 and 228, to get
228 = 188 x 1 + 40
Step 3: We consider the new divisor 188 and the new remainder 40, and apply the division lemma to get
188 = 40 x 4 + 28
We consider the new divisor 40 and the new remainder 28,and apply the division lemma to get
40 = 28 x 1 + 12
We consider the new divisor 28 and the new remainder 12,and apply the division lemma to get
28 = 12 x 2 + 4
We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 228 and 872 is 4
Notice that 4 = HCF(12,4) = HCF(28,12) = HCF(40,28) = HCF(188,40) = HCF(228,188) = HCF(872,228) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 20 > 4, we apply the division lemma to 20 and 4, to get
20 = 4 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 20 is 4
Notice that 4 = HCF(20,4) .
