HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 328, 378, 657, 940 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 328, 378, 657, 940 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 328, 378, 657, 940 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 328, 378, 657, 940 is 1.
HCF(328, 378, 657, 940) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 328, 378, 657, 940 is 1.
Step 1: Since 378 > 328, we apply the division lemma to 378 and 328, to get
378 = 328 x 1 + 50
Step 2: Since the reminder 328 ≠ 0, we apply division lemma to 50 and 328, to get
328 = 50 x 6 + 28
Step 3: We consider the new divisor 50 and the new remainder 28, and apply the division lemma to get
50 = 28 x 1 + 22
We consider the new divisor 28 and the new remainder 22,and apply the division lemma to get
28 = 22 x 1 + 6
We consider the new divisor 22 and the new remainder 6,and apply the division lemma to get
22 = 6 x 3 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 328 and 378 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(22,6) = HCF(28,22) = HCF(50,28) = HCF(328,50) = HCF(378,328) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 657 > 2, we apply the division lemma to 657 and 2, to get
657 = 2 x 328 + 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 657 is 1
Notice that 1 = HCF(2,1) = HCF(657,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 940 > 1, we apply the division lemma to 940 and 1, to get
940 = 1 x 940 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 940 is 1
Notice that 1 = HCF(940,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
