HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 340, 916, 425 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 340, 916, 425 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 340, 916, 425 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 340, 916, 425 is 1.
HCF(340, 916, 425) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 340, 916, 425 is 1.
Step 1: Since 916 > 340, we apply the division lemma to 916 and 340, to get
916 = 340 x 2 + 236
Step 2: Since the reminder 340 ≠ 0, we apply division lemma to 236 and 340, to get
340 = 236 x 1 + 104
Step 3: We consider the new divisor 236 and the new remainder 104, and apply the division lemma to get
236 = 104 x 2 + 28
We consider the new divisor 104 and the new remainder 28,and apply the division lemma to get
104 = 28 x 3 + 20
We consider the new divisor 28 and the new remainder 20,and apply the division lemma to get
28 = 20 x 1 + 8
We consider the new divisor 20 and the new remainder 8,and apply the division lemma to get
20 = 8 x 2 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 340 and 916 is 4
Notice that 4 = HCF(8,4) = HCF(20,8) = HCF(28,20) = HCF(104,28) = HCF(236,104) = HCF(340,236) = HCF(916,340) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 425 > 4, we apply the division lemma to 425 and 4, to get
425 = 4 x 106 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 425 is 1
Notice that 1 = HCF(4,1) = HCF(425,4) .
Here are some samples of HCF using Euclid's Algorithm calculations.
