HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 275, 1355 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 275, 1355 is 5 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 275, 1355 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 275, 1355 is 5.
HCF(275, 1355) = 5
HCF of 275, 1355 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 275, 1355 is 5.
Highest Common Factor of 275,1355 is 5
Step 1: Since 1355 > 275, we apply the division lemma to 1355 and 275, to get
1355 = 275 x 4 + 255
Step 2: Since the reminder 275 ≠ 0, we apply division lemma to 255 and 275, to get
275 = 255 x 1 + 20
Step 3: We consider the new divisor 255 and the new remainder 20, and apply the division lemma to get
255 = 20 x 12 + 15
We consider the new divisor 20 and the new remainder 15,and apply the division lemma to get
20 = 15 x 1 + 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 275 and 1355 is 5
Notice that 5 = HCF(15,5) = HCF(20,15) = HCF(255,20) = HCF(275,255) = HCF(1355,275) .
