HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 855, 64898 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 855, 64898 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 855, 64898 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 855, 64898 is 1.
HCF(855, 64898) = 1
HCF of 855, 64898 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 855, 64898 is 1.
Highest Common Factor of 855,64898 is 1
Step 1: Since 64898 > 855, we apply the division lemma to 64898 and 855, to get
64898 = 855 x 75 + 773
Step 2: Since the reminder 855 ≠ 0, we apply division lemma to 773 and 855, to get
855 = 773 x 1 + 82
Step 3: We consider the new divisor 773 and the new remainder 82, and apply the division lemma to get
773 = 82 x 9 + 35
We consider the new divisor 82 and the new remainder 35,and apply the division lemma to get
82 = 35 x 2 + 12
We consider the new divisor 35 and the new remainder 12,and apply the division lemma to get
35 = 12 x 2 + 11
We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 855 and 64898 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(35,12) = HCF(82,35) = HCF(773,82) = HCF(855,773) = HCF(64898,855) .
