HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 120, 568, 986, 63 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 120, 568, 986, 63 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 120, 568, 986, 63 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, 568, 986, 63 is 1.
HCF(120, 568, 986, 63) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 120, 568, 986, 63 is 1.
Step 1: Since 568 > 120, we apply the division lemma to 568 and 120, to get
568 = 120 x 4 + 88
Step 2: Since the reminder 120 ≠ 0, we apply division lemma to 88 and 120, to get
120 = 88 x 1 + 32
Step 3: We consider the new divisor 88 and the new remainder 32, and apply the division lemma to get
88 = 32 x 2 + 24
We consider the new divisor 32 and the new remainder 24,and apply the division lemma to get
32 = 24 x 1 + 8
We consider the new divisor 24 and the new remainder 8,and apply the division lemma to get
24 = 8 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 120 and 568 is 8
Notice that 8 = HCF(24,8) = HCF(32,24) = HCF(88,32) = HCF(120,88) = HCF(568,120) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 986 > 8, we apply the division lemma to 986 and 8, to get
986 = 8 x 123 + 2
Step 2: Since the reminder 8 ≠ 0, we apply division lemma to 2 and 8, to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 8 and 986 is 2
Notice that 2 = HCF(8,2) = HCF(986,8) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 63 > 2, we apply the division lemma to 63 and 2, to get
63 = 2 x 31 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 63 is 1
Notice that 1 = HCF(2,1) = HCF(63,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
