HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 196, 915, 509 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 196, 915, 509 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 196, 915, 509 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 196, 915, 509 is 1.
HCF(196, 915, 509) = 1
HCF of 196, 915, 509 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 196, 915, 509 is 1.
Highest Common Factor of 196,915,509 is 1
Step 1: Since 915 > 196, we apply the division lemma to 915 and 196, to get
915 = 196 x 4 + 131
Step 2: Since the reminder 196 ≠ 0, we apply division lemma to 131 and 196, to get
196 = 131 x 1 + 65
Step 3: We consider the new divisor 131 and the new remainder 65, and apply the division lemma to get
131 = 65 x 2 + 1
We consider the new divisor 65 and the new remainder 1, and apply the division lemma to get
65 = 1 x 65 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 196 and 915 is 1
Notice that 1 = HCF(65,1) = HCF(131,65) = HCF(196,131) = HCF(915,196) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 509 > 1, we apply the division lemma to 509 and 1, to get
509 = 1 x 509 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 509 is 1
Notice that 1 = HCF(509,1) .
