HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 915, 834, 402 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 915, 834, 402 is 3 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 915, 834, 402 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 915, 834, 402 is 3.
HCF(915, 834, 402) = 3
HCF of 915, 834, 402 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 915, 834, 402 is 3.
Highest Common Factor of 915,834,402 is 3
Step 1: Since 915 > 834, we apply the division lemma to 915 and 834, to get
915 = 834 x 1 + 81
Step 2: Since the reminder 834 ≠ 0, we apply division lemma to 81 and 834, to get
834 = 81 x 10 + 24
Step 3: We consider the new divisor 81 and the new remainder 24, and apply the division lemma to get
81 = 24 x 3 + 9
We consider the new divisor 24 and the new remainder 9,and apply the division lemma to get
24 = 9 x 2 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 915 and 834 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(24,9) = HCF(81,24) = HCF(834,81) = HCF(915,834) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 402 > 3, we apply the division lemma to 402 and 3, to get
402 = 3 x 134 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 402 is 3
Notice that 3 = HCF(402,3) .
