HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 618, 858, 887 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 618, 858, 887 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 618, 858, 887 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 618, 858, 887 is 1.
HCF(618, 858, 887) = 1
HCF of 618, 858, 887 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 618, 858, 887 is 1.
Highest Common Factor of 618,858,887 is 1
Step 1: Since 858 > 618, we apply the division lemma to 858 and 618, to get
858 = 618 x 1 + 240
Step 2: Since the reminder 618 ≠ 0, we apply division lemma to 240 and 618, to get
618 = 240 x 2 + 138
Step 3: We consider the new divisor 240 and the new remainder 138, and apply the division lemma to get
240 = 138 x 1 + 102
We consider the new divisor 138 and the new remainder 102,and apply the division lemma to get
138 = 102 x 1 + 36
We consider the new divisor 102 and the new remainder 36,and apply the division lemma to get
102 = 36 x 2 + 30
We consider the new divisor 36 and the new remainder 30,and apply the division lemma to get
36 = 30 x 1 + 6
We consider the new divisor 30 and the new remainder 6,and apply the division lemma to get
30 = 6 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 618 and 858 is 6
Notice that 6 = HCF(30,6) = HCF(36,30) = HCF(102,36) = HCF(138,102) = HCF(240,138) = HCF(618,240) = HCF(858,618) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 887 > 6, we apply the division lemma to 887 and 6, to get
887 = 6 x 147 + 5
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 5 and 6, to get
6 = 5 x 1 + 1
Step 3: We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 6 and 887 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(887,6) .
