HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 705, 394, 378 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 705, 394, 378 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 705, 394, 378 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 705, 394, 378 is 1.
HCF(705, 394, 378) = 1
HCF of 705, 394, 378 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 705, 394, 378 is 1.
Highest Common Factor of 705,394,378 is 1
Step 1: Since 705 > 394, we apply the division lemma to 705 and 394, to get
705 = 394 x 1 + 311
Step 2: Since the reminder 394 ≠ 0, we apply division lemma to 311 and 394, to get
394 = 311 x 1 + 83
Step 3: We consider the new divisor 311 and the new remainder 83, and apply the division lemma to get
311 = 83 x 3 + 62
We consider the new divisor 83 and the new remainder 62,and apply the division lemma to get
83 = 62 x 1 + 21
We consider the new divisor 62 and the new remainder 21,and apply the division lemma to get
62 = 21 x 2 + 20
We consider the new divisor 21 and the new remainder 20,and apply the division lemma to get
21 = 20 x 1 + 1
We consider the new divisor 20 and the new remainder 1,and apply the division lemma to get
20 = 1 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 705 and 394 is 1
Notice that 1 = HCF(20,1) = HCF(21,20) = HCF(62,21) = HCF(83,62) = HCF(311,83) = HCF(394,311) = HCF(705,394) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 378 > 1, we apply the division lemma to 378 and 1, to get
378 = 1 x 378 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 378 is 1
Notice that 1 = HCF(378,1) .
