HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 456, 284, 89 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 456, 284, 89 is 1 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 456, 284, 89 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 456, 284, 89 is 1.
HCF(456, 284, 89) = 1
HCF of 456, 284, 89 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 456, 284, 89 is 1.
Highest Common Factor of 456,284,89 is 1
Step 1: Since 456 > 284, we apply the division lemma to 456 and 284, to get
456 = 284 x 1 + 172
Step 2: Since the reminder 284 ≠ 0, we apply division lemma to 172 and 284, to get
284 = 172 x 1 + 112
Step 3: We consider the new divisor 172 and the new remainder 112, and apply the division lemma to get
172 = 112 x 1 + 60
We consider the new divisor 112 and the new remainder 60,and apply the division lemma to get
112 = 60 x 1 + 52
We consider the new divisor 60 and the new remainder 52,and apply the division lemma to get
60 = 52 x 1 + 8
We consider the new divisor 52 and the new remainder 8,and apply the division lemma to get
52 = 8 x 6 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 456 and 284 is 4
Notice that 4 = HCF(8,4) = HCF(52,8) = HCF(60,52) = HCF(112,60) = HCF(172,112) = HCF(284,172) = HCF(456,284) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 89 > 4, we apply the division lemma to 89 and 4, to get
89 = 4 x 22 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 89 is 1
Notice that 1 = HCF(4,1) = HCF(89,4) .
