HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 840, 935, 273 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 840, 935, 273 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 840, 935, 273 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 840, 935, 273 is 1.
HCF(840, 935, 273) = 1
HCF of 840, 935, 273 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 840, 935, 273 is 1.
Highest Common Factor of 840,935,273 is 1
Step 1: Since 935 > 840, we apply the division lemma to 935 and 840, to get
935 = 840 x 1 + 95
Step 2: Since the reminder 840 ≠ 0, we apply division lemma to 95 and 840, to get
840 = 95 x 8 + 80
Step 3: We consider the new divisor 95 and the new remainder 80, and apply the division lemma to get
95 = 80 x 1 + 15
We consider the new divisor 80 and the new remainder 15,and apply the division lemma to get
80 = 15 x 5 + 5
We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 840 and 935 is 5
Notice that 5 = HCF(15,5) = HCF(80,15) = HCF(95,80) = HCF(840,95) = HCF(935,840) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 273 > 5, we apply the division lemma to 273 and 5, to get
273 = 5 x 54 + 3
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get
5 = 3 x 1 + 2
Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 273 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(273,5) .
