HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 39, 23, 929, 970 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 39, 23, 929, 970 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 39, 23, 929, 970 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 39, 23, 929, 970 is 1.
HCF(39, 23, 929, 970) = 1
HCF of 39, 23, 929, 970 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 39, 23, 929, 970 is 1.
Highest Common Factor of 39,23,929,970 is 1
Step 1: Since 39 > 23, we apply the division lemma to 39 and 23, to get
39 = 23 x 1 + 16
Step 2: Since the reminder 23 ≠ 0, we apply division lemma to 16 and 23, to get
23 = 16 x 1 + 7
Step 3: We consider the new divisor 16 and the new remainder 7, and apply the division lemma to get
16 = 7 x 2 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 39 and 23 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(23,16) = HCF(39,23) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 929 > 1, we apply the division lemma to 929 and 1, to get
929 = 1 x 929 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 929 is 1
Notice that 1 = HCF(929,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 970 > 1, we apply the division lemma to 970 and 1, to get
970 = 1 x 970 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 970 is 1
Notice that 1 = HCF(970,1) .
