HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 275, 755 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 275, 755 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, 755 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, 755 is 5.
HCF(275, 755) = 5
HCF of 275, 755 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, 755 is 5.
Highest Common Factor of 275,755 is 5
Step 1: Since 755 > 275, we apply the division lemma to 755 and 275, to get
755 = 275 x 2 + 205
Step 2: Since the reminder 275 ≠ 0, we apply division lemma to 205 and 275, to get
275 = 205 x 1 + 70
Step 3: We consider the new divisor 205 and the new remainder 70, and apply the division lemma to get
205 = 70 x 2 + 65
We consider the new divisor 70 and the new remainder 65,and apply the division lemma to get
70 = 65 x 1 + 5
We consider the new divisor 65 and the new remainder 5,and apply the division lemma to get
65 = 5 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 275 and 755 is 5
Notice that 5 = HCF(65,5) = HCF(70,65) = HCF(205,70) = HCF(275,205) = HCF(755,275) .
