HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 755, 69125 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 755, 69125 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 755, 69125 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 755, 69125 is 5.
HCF(755, 69125) = 5
HCF of 755, 69125 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 755, 69125 is 5.
Highest Common Factor of 755,69125 is 5
Step 1: Since 69125 > 755, we apply the division lemma to 69125 and 755, to get
69125 = 755 x 91 + 420
Step 2: Since the reminder 755 ≠ 0, we apply division lemma to 420 and 755, to get
755 = 420 x 1 + 335
Step 3: We consider the new divisor 420 and the new remainder 335, and apply the division lemma to get
420 = 335 x 1 + 85
We consider the new divisor 335 and the new remainder 85,and apply the division lemma to get
335 = 85 x 3 + 80
We consider the new divisor 85 and the new remainder 80,and apply the division lemma to get
85 = 80 x 1 + 5
We consider the new divisor 80 and the new remainder 5,and apply the division lemma to get
80 = 5 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 755 and 69125 is 5
Notice that 5 = HCF(80,5) = HCF(85,80) = HCF(335,85) = HCF(420,335) = HCF(755,420) = HCF(69125,755) .
