HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 948, 393, 70 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 948, 393, 70 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 948, 393, 70 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 948, 393, 70 is 1.
HCF(948, 393, 70) = 1
HCF of 948, 393, 70 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 948, 393, 70 is 1.
Highest Common Factor of 948,393,70 is 1
Step 1: Since 948 > 393, we apply the division lemma to 948 and 393, to get
948 = 393 x 2 + 162
Step 2: Since the reminder 393 ≠ 0, we apply division lemma to 162 and 393, to get
393 = 162 x 2 + 69
Step 3: We consider the new divisor 162 and the new remainder 69, and apply the division lemma to get
162 = 69 x 2 + 24
We consider the new divisor 69 and the new remainder 24,and apply the division lemma to get
69 = 24 x 2 + 21
We consider the new divisor 24 and the new remainder 21,and apply the division lemma to get
24 = 21 x 1 + 3
We consider the new divisor 21 and the new remainder 3,and apply the division lemma to get
21 = 3 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 948 and 393 is 3
Notice that 3 = HCF(21,3) = HCF(24,21) = HCF(69,24) = HCF(162,69) = HCF(393,162) = HCF(948,393) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 70 > 3, we apply the division lemma to 70 and 3, to get
70 = 3 x 23 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 70 is 1
Notice that 1 = HCF(3,1) = HCF(70,3) .
