HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 715, 800, 445 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 715, 800, 445 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 715, 800, 445 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 715, 800, 445 is 5.
HCF(715, 800, 445) = 5
HCF of 715, 800, 445 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 715, 800, 445 is 5.
Highest Common Factor of 715,800,445 is 5
Step 1: Since 800 > 715, we apply the division lemma to 800 and 715, to get
800 = 715 x 1 + 85
Step 2: Since the reminder 715 ≠ 0, we apply division lemma to 85 and 715, to get
715 = 85 x 8 + 35
Step 3: We consider the new divisor 85 and the new remainder 35, and apply the division lemma to get
85 = 35 x 2 + 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 715 and 800 is 5
Notice that 5 = HCF(15,5) = HCF(35,15) = HCF(85,35) = HCF(715,85) = HCF(800,715) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 445 > 5, we apply the division lemma to 445 and 5, to get
445 = 5 x 89 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 445 is 5
Notice that 5 = HCF(445,5) .
