HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 458, 789, 888 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 458, 789, 888 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 458, 789, 888 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 458, 789, 888 is 1.
HCF(458, 789, 888) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 458, 789, 888 is 1.
Step 1: Since 789 > 458, we apply the division lemma to 789 and 458, to get
789 = 458 x 1 + 331
Step 2: Since the reminder 458 ≠ 0, we apply division lemma to 331 and 458, to get
458 = 331 x 1 + 127
Step 3: We consider the new divisor 331 and the new remainder 127, and apply the division lemma to get
331 = 127 x 2 + 77
We consider the new divisor 127 and the new remainder 77,and apply the division lemma to get
127 = 77 x 1 + 50
We consider the new divisor 77 and the new remainder 50,and apply the division lemma to get
77 = 50 x 1 + 27
We consider the new divisor 50 and the new remainder 27,and apply the division lemma to get
50 = 27 x 1 + 23
We consider the new divisor 27 and the new remainder 23,and apply the division lemma to get
27 = 23 x 1 + 4
We consider the new divisor 23 and the new remainder 4,and apply the division lemma to get
23 = 4 x 5 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 458 and 789 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(23,4) = HCF(27,23) = HCF(50,27) = HCF(77,50) = HCF(127,77) = HCF(331,127) = HCF(458,331) = HCF(789,458) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 888 > 1, we apply the division lemma to 888 and 1, to get
888 = 1 x 888 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 888 is 1
Notice that 1 = HCF(888,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
