HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 745, 73495 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 745, 73495 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 745, 73495 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 745, 73495 is 5.
HCF(745, 73495) = 5
HCF of 745, 73495 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 745, 73495 is 5.
Highest Common Factor of 745,73495 is 5
Step 1: Since 73495 > 745, we apply the division lemma to 73495 and 745, to get
73495 = 745 x 98 + 485
Step 2: Since the reminder 745 ≠ 0, we apply division lemma to 485 and 745, to get
745 = 485 x 1 + 260
Step 3: We consider the new divisor 485 and the new remainder 260, and apply the division lemma to get
485 = 260 x 1 + 225
We consider the new divisor 260 and the new remainder 225,and apply the division lemma to get
260 = 225 x 1 + 35
We consider the new divisor 225 and the new remainder 35,and apply the division lemma to get
225 = 35 x 6 + 15
We consider the new divisor 35 and the new remainder 15,and apply the division lemma to get
35 = 15 x 2 + 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 745 and 73495 is 5
Notice that 5 = HCF(15,5) = HCF(35,15) = HCF(225,35) = HCF(260,225) = HCF(485,260) = HCF(745,485) = HCF(73495,745) .
