HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 85, 138, 903 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 85, 138, 903 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 85, 138, 903 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 85, 138, 903 is 1.
HCF(85, 138, 903) = 1
HCF of 85, 138, 903 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 85, 138, 903 is 1.
Highest Common Factor of 85,138,903 is 1
Step 1: Since 138 > 85, we apply the division lemma to 138 and 85, to get
138 = 85 x 1 + 53
Step 2: Since the reminder 85 ≠ 0, we apply division lemma to 53 and 85, to get
85 = 53 x 1 + 32
Step 3: We consider the new divisor 53 and the new remainder 32, and apply the division lemma to get
53 = 32 x 1 + 21
We consider the new divisor 32 and the new remainder 21,and apply the division lemma to get
32 = 21 x 1 + 11
We consider the new divisor 21 and the new remainder 11,and apply the division lemma to get
21 = 11 x 1 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 85 and 138 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(21,11) = HCF(32,21) = HCF(53,32) = HCF(85,53) = HCF(138,85) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 903 > 1, we apply the division lemma to 903 and 1, to get
903 = 1 x 903 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 903 is 1
Notice that 1 = HCF(903,1) .
