HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 865, 715, 507 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 865, 715, 507 is 1 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 865, 715, 507 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 865, 715, 507 is 1.
HCF(865, 715, 507) = 1
HCF of 865, 715, 507 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 865, 715, 507 is 1.
Highest Common Factor of 865,715,507 is 1
Step 1: Since 865 > 715, we apply the division lemma to 865 and 715, to get
865 = 715 x 1 + 150
Step 2: Since the reminder 715 ≠ 0, we apply division lemma to 150 and 715, to get
715 = 150 x 4 + 115
Step 3: We consider the new divisor 150 and the new remainder 115, and apply the division lemma to get
150 = 115 x 1 + 35
We consider the new divisor 115 and the new remainder 35,and apply the division lemma to get
115 = 35 x 3 + 10
We consider the new divisor 35 and the new remainder 10,and apply the division lemma to get
35 = 10 x 3 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 865 and 715 is 5
Notice that 5 = HCF(10,5) = HCF(35,10) = HCF(115,35) = HCF(150,115) = HCF(715,150) = HCF(865,715) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 507 > 5, we apply the division lemma to 507 and 5, to get
507 = 5 x 101 + 2
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 2 and 5, to get
5 = 2 x 2 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 507 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(507,5) .
