HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 967, 515, 42 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 967, 515, 42 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 967, 515, 42 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 967, 515, 42 is 1.
HCF(967, 515, 42) = 1
HCF of 967, 515, 42 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 967, 515, 42 is 1.
Highest Common Factor of 967,515,42 is 1
Step 1: Since 967 > 515, we apply the division lemma to 967 and 515, to get
967 = 515 x 1 + 452
Step 2: Since the reminder 515 ≠ 0, we apply division lemma to 452 and 515, to get
515 = 452 x 1 + 63
Step 3: We consider the new divisor 452 and the new remainder 63, and apply the division lemma to get
452 = 63 x 7 + 11
We consider the new divisor 63 and the new remainder 11,and apply the division lemma to get
63 = 11 x 5 + 8
We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get
11 = 8 x 1 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 967 and 515 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(63,11) = HCF(452,63) = HCF(515,452) = HCF(967,515) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 42 > 1, we apply the division lemma to 42 and 1, to get
42 = 1 x 42 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 42 is 1
Notice that 1 = HCF(42,1) .
