HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 545, 935, 869 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 545, 935, 869 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 545, 935, 869 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 545, 935, 869 is 1.
HCF(545, 935, 869) = 1
HCF of 545, 935, 869 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 545, 935, 869 is 1.
Highest Common Factor of 545,935,869 is 1
Step 1: Since 935 > 545, we apply the division lemma to 935 and 545, to get
935 = 545 x 1 + 390
Step 2: Since the reminder 545 ≠ 0, we apply division lemma to 390 and 545, to get
545 = 390 x 1 + 155
Step 3: We consider the new divisor 390 and the new remainder 155, and apply the division lemma to get
390 = 155 x 2 + 80
We consider the new divisor 155 and the new remainder 80,and apply the division lemma to get
155 = 80 x 1 + 75
We consider the new divisor 80 and the new remainder 75,and apply the division lemma to get
80 = 75 x 1 + 5
We consider the new divisor 75 and the new remainder 5,and apply the division lemma to get
75 = 5 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 545 and 935 is 5
Notice that 5 = HCF(75,5) = HCF(80,75) = HCF(155,80) = HCF(390,155) = HCF(545,390) = HCF(935,545) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 869 > 5, we apply the division lemma to 869 and 5, to get
869 = 5 x 173 + 4
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get
5 = 4 x 1 + 1
Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 869 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(869,5) .
