HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 930, 790, 705 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 930, 790, 705 is 5 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 930, 790, 705 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 930, 790, 705 is 5.
HCF(930, 790, 705) = 5
HCF of 930, 790, 705 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 930, 790, 705 is 5.
Highest Common Factor of 930,790,705 is 5
Step 1: Since 930 > 790, we apply the division lemma to 930 and 790, to get
930 = 790 x 1 + 140
Step 2: Since the reminder 790 ≠ 0, we apply division lemma to 140 and 790, to get
790 = 140 x 5 + 90
Step 3: We consider the new divisor 140 and the new remainder 90, and apply the division lemma to get
140 = 90 x 1 + 50
We consider the new divisor 90 and the new remainder 50,and apply the division lemma to get
90 = 50 x 1 + 40
We consider the new divisor 50 and the new remainder 40,and apply the division lemma to get
50 = 40 x 1 + 10
We consider the new divisor 40 and the new remainder 10,and apply the division lemma to get
40 = 10 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 930 and 790 is 10
Notice that 10 = HCF(40,10) = HCF(50,40) = HCF(90,50) = HCF(140,90) = HCF(790,140) = HCF(930,790) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 705 > 10, we apply the division lemma to 705 and 10, to get
705 = 10 x 70 + 5
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 5 and 10, to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 10 and 705 is 5
Notice that 5 = HCF(10,5) = HCF(705,10) .
