HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 974, 340, 485 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 974, 340, 485 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 974, 340, 485 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 974, 340, 485 is 1.
HCF(974, 340, 485) = 1
HCF of 974, 340, 485 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 974, 340, 485 is 1.
Highest Common Factor of 974,340,485 is 1
Step 1: Since 974 > 340, we apply the division lemma to 974 and 340, to get
974 = 340 x 2 + 294
Step 2: Since the reminder 340 ≠ 0, we apply division lemma to 294 and 340, to get
340 = 294 x 1 + 46
Step 3: We consider the new divisor 294 and the new remainder 46, and apply the division lemma to get
294 = 46 x 6 + 18
We consider the new divisor 46 and the new remainder 18,and apply the division lemma to get
46 = 18 x 2 + 10
We consider the new divisor 18 and the new remainder 10,and apply the division lemma to get
18 = 10 x 1 + 8
We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get
10 = 8 x 1 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 974 and 340 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(18,10) = HCF(46,18) = HCF(294,46) = HCF(340,294) = HCF(974,340) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 485 > 2, we apply the division lemma to 485 and 2, to get
485 = 2 x 242 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 485 is 1
Notice that 1 = HCF(2,1) = HCF(485,2) .
