HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 515, 931, 146 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 515, 931, 146 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 515, 931, 146 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 515, 931, 146 is 1.
HCF(515, 931, 146) = 1
HCF of 515, 931, 146 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 515, 931, 146 is 1.
Highest Common Factor of 515,931,146 is 1
Step 1: Since 931 > 515, we apply the division lemma to 931 and 515, to get
931 = 515 x 1 + 416
Step 2: Since the reminder 515 ≠ 0, we apply division lemma to 416 and 515, to get
515 = 416 x 1 + 99
Step 3: We consider the new divisor 416 and the new remainder 99, and apply the division lemma to get
416 = 99 x 4 + 20
We consider the new divisor 99 and the new remainder 20,and apply the division lemma to get
99 = 20 x 4 + 19
We consider the new divisor 20 and the new remainder 19,and apply the division lemma to get
20 = 19 x 1 + 1
We consider the new divisor 19 and the new remainder 1,and apply the division lemma to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 515 and 931 is 1
Notice that 1 = HCF(19,1) = HCF(20,19) = HCF(99,20) = HCF(416,99) = HCF(515,416) = HCF(931,515) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 146 > 1, we apply the division lemma to 146 and 1, to get
146 = 1 x 146 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 146 is 1
Notice that 1 = HCF(146,1) .
