HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 67, 90, 42, 651 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 67, 90, 42, 651 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 67, 90, 42, 651 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 67, 90, 42, 651 is 1.
HCF(67, 90, 42, 651) = 1
HCF of 67, 90, 42, 651 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 67, 90, 42, 651 is 1.
Highest Common Factor of 67,90,42,651 is 1
Step 1: Since 90 > 67, we apply the division lemma to 90 and 67, to get
90 = 67 x 1 + 23
Step 2: Since the reminder 67 ≠ 0, we apply division lemma to 23 and 67, to get
67 = 23 x 2 + 21
Step 3: We consider the new divisor 23 and the new remainder 21, and apply the division lemma to get
23 = 21 x 1 + 2
We consider the new divisor 21 and the new remainder 2,and apply the division lemma to get
21 = 2 x 10 + 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 67 and 90 is 1
Notice that 1 = HCF(2,1) = HCF(21,2) = HCF(23,21) = HCF(67,23) = HCF(90,67) .
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) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 651 > 1, we apply the division lemma to 651 and 1, to get
651 = 1 x 651 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 651 is 1
Notice that 1 = HCF(651,1) .
