HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 451, 891, 858 i.e. 11 the largest integer that leaves a remainder zero for all numbers.
HCF of 451, 891, 858 is 11 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 451, 891, 858 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 451, 891, 858 is 11.
HCF(451, 891, 858) = 11
HCF of 451, 891, 858 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 451, 891, 858 is 11.
Highest Common Factor of 451,891,858 is 11
Step 1: Since 891 > 451, we apply the division lemma to 891 and 451, to get
891 = 451 x 1 + 440
Step 2: Since the reminder 451 ≠ 0, we apply division lemma to 440 and 451, to get
451 = 440 x 1 + 11
Step 3: We consider the new divisor 440 and the new remainder 11, and apply the division lemma to get
440 = 11 x 40 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 451 and 891 is 11
Notice that 11 = HCF(440,11) = HCF(451,440) = HCF(891,451) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 858 > 11, we apply the division lemma to 858 and 11, to get
858 = 11 x 78 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 11 and 858 is 11
Notice that 11 = HCF(858,11) .
