HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 968, 154, 123, 587 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 968, 154, 123, 587 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 968, 154, 123, 587 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 968, 154, 123, 587 is 1.
HCF(968, 154, 123, 587) = 1
HCF of 968, 154, 123, 587 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 968, 154, 123, 587 is 1.
Highest Common Factor of 968,154,123,587 is 1
Step 1: Since 968 > 154, we apply the division lemma to 968 and 154, to get
968 = 154 x 6 + 44
Step 2: Since the reminder 154 ≠ 0, we apply division lemma to 44 and 154, to get
154 = 44 x 3 + 22
Step 3: We consider the new divisor 44 and the new remainder 22, and apply the division lemma to get
44 = 22 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 22, the HCF of 968 and 154 is 22
Notice that 22 = HCF(44,22) = HCF(154,44) = HCF(968,154) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 123 > 22, we apply the division lemma to 123 and 22, to get
123 = 22 x 5 + 13
Step 2: Since the reminder 22 ≠ 0, we apply division lemma to 13 and 22, to get
22 = 13 x 1 + 9
Step 3: We consider the new divisor 13 and the new remainder 9, and apply the division lemma to get
13 = 9 x 1 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 22 and 123 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(22,13) = HCF(123,22) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 587 > 1, we apply the division lemma to 587 and 1, to get
587 = 1 x 587 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 587 is 1
Notice that 1 = HCF(587,1) .
