HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 389, 909, 901 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 389, 909, 901 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 389, 909, 901 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 389, 909, 901 is 1.
HCF(389, 909, 901) = 1
HCF of 389, 909, 901 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 389, 909, 901 is 1.
Highest Common Factor of 389,909,901 is 1
Step 1: Since 909 > 389, we apply the division lemma to 909 and 389, to get
909 = 389 x 2 + 131
Step 2: Since the reminder 389 ≠ 0, we apply division lemma to 131 and 389, to get
389 = 131 x 2 + 127
Step 3: We consider the new divisor 131 and the new remainder 127, and apply the division lemma to get
131 = 127 x 1 + 4
We consider the new divisor 127 and the new remainder 4,and apply the division lemma to get
127 = 4 x 31 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 389 and 909 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(127,4) = HCF(131,127) = HCF(389,131) = HCF(909,389) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 901 > 1, we apply the division lemma to 901 and 1, to get
901 = 1 x 901 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 901 is 1
Notice that 1 = HCF(901,1) .
