HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 989, 855 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 989, 855 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 989, 855 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 989, 855 is 1.
HCF(989, 855) = 1
HCF of 989, 855 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 989, 855 is 1.
Highest Common Factor of 989,855 is 1
Step 1: Since 989 > 855, we apply the division lemma to 989 and 855, to get
989 = 855 x 1 + 134
Step 2: Since the reminder 855 ≠ 0, we apply division lemma to 134 and 855, to get
855 = 134 x 6 + 51
Step 3: We consider the new divisor 134 and the new remainder 51, and apply the division lemma to get
134 = 51 x 2 + 32
We consider the new divisor 51 and the new remainder 32,and apply the division lemma to get
51 = 32 x 1 + 19
We consider the new divisor 32 and the new remainder 19,and apply the division lemma to get
32 = 19 x 1 + 13
We consider the new divisor 19 and the new remainder 13,and apply the division lemma to get
19 = 13 x 1 + 6
We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get
13 = 6 x 2 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 989 and 855 is 1
Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(19,13) = HCF(32,19) = HCF(51,32) = HCF(134,51) = HCF(855,134) = HCF(989,855) .
