HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 138, 853 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 138, 853 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 138, 853 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 138, 853 is 1.
HCF(138, 853) = 1
HCF of 138, 853 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 138, 853 is 1.
Highest Common Factor of 138,853 is 1
Step 1: Since 853 > 138, we apply the division lemma to 853 and 138, to get
853 = 138 x 6 + 25
Step 2: Since the reminder 138 ≠ 0, we apply division lemma to 25 and 138, to get
138 = 25 x 5 + 13
Step 3: We consider the new divisor 25 and the new remainder 13, and apply the division lemma to get
25 = 13 x 1 + 12
We consider the new divisor 13 and the new remainder 12,and apply the division lemma to get
13 = 12 x 1 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 138 and 853 is 1
Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(25,13) = HCF(138,25) = HCF(853,138) .
