HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 273, 413, 90 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 273, 413, 90 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 273, 413, 90 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 273, 413, 90 is 1.
HCF(273, 413, 90) = 1
HCF of 273, 413, 90 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 273, 413, 90 is 1.
Highest Common Factor of 273,413,90 is 1
Step 1: Since 413 > 273, we apply the division lemma to 413 and 273, to get
413 = 273 x 1 + 140
Step 2: Since the reminder 273 ≠ 0, we apply division lemma to 140 and 273, to get
273 = 140 x 1 + 133
Step 3: We consider the new divisor 140 and the new remainder 133, and apply the division lemma to get
140 = 133 x 1 + 7
We consider the new divisor 133 and the new remainder 7, and apply the division lemma to get
133 = 7 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 273 and 413 is 7
Notice that 7 = HCF(133,7) = HCF(140,133) = HCF(273,140) = HCF(413,273) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 90 > 7, we apply the division lemma to 90 and 7, to get
90 = 7 x 12 + 6
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 6 and 7, to get
7 = 6 x 1 + 1
Step 3: We consider the new divisor 6 and the new remainder 1, and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 90 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(90,7) .
