HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 853, 618 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 853, 618 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 853, 618 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 853, 618 is 1.
HCF(853, 618) = 1
HCF of 853, 618 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 853, 618 is 1.
Highest Common Factor of 853,618 is 1
Step 1: Since 853 > 618, we apply the division lemma to 853 and 618, to get
853 = 618 x 1 + 235
Step 2: Since the reminder 618 ≠ 0, we apply division lemma to 235 and 618, to get
618 = 235 x 2 + 148
Step 3: We consider the new divisor 235 and the new remainder 148, and apply the division lemma to get
235 = 148 x 1 + 87
We consider the new divisor 148 and the new remainder 87,and apply the division lemma to get
148 = 87 x 1 + 61
We consider the new divisor 87 and the new remainder 61,and apply the division lemma to get
87 = 61 x 1 + 26
We consider the new divisor 61 and the new remainder 26,and apply the division lemma to get
61 = 26 x 2 + 9
We consider the new divisor 26 and the new remainder 9,and apply the division lemma to get
26 = 9 x 2 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 853 and 618 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(26,9) = HCF(61,26) = HCF(87,61) = HCF(148,87) = HCF(235,148) = HCF(618,235) = HCF(853,618) .
