HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 120, 582, 858, 69 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 120, 582, 858, 69 is 3 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 120, 582, 858, 69 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 120, 582, 858, 69 is 3.
HCF(120, 582, 858, 69) = 3
HCF of 120, 582, 858, 69 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 120, 582, 858, 69 is 3.
Highest Common Factor of 120,582,858,69 is 3
Step 1: Since 582 > 120, we apply the division lemma to 582 and 120, to get
582 = 120 x 4 + 102
Step 2: Since the reminder 120 ≠ 0, we apply division lemma to 102 and 120, to get
120 = 102 x 1 + 18
Step 3: We consider the new divisor 102 and the new remainder 18, and apply the division lemma to get
102 = 18 x 5 + 12
We consider the new divisor 18 and the new remainder 12,and apply the division lemma to get
18 = 12 x 1 + 6
We consider the new divisor 12 and the new remainder 6,and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 120 and 582 is 6
Notice that 6 = HCF(12,6) = HCF(18,12) = HCF(102,18) = HCF(120,102) = HCF(582,120) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 858 > 6, we apply the division lemma to 858 and 6, to get
858 = 6 x 143 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 6 and 858 is 6
Notice that 6 = HCF(858,6) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 69 > 6, we apply the division lemma to 69 and 6, to get
69 = 6 x 11 + 3
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 3 and 6, to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 6 and 69 is 3
Notice that 3 = HCF(6,3) = HCF(69,6) .
