HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 984, 612, 128 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 984, 612, 128 is 4 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 984, 612, 128 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 984, 612, 128 is 4.
HCF(984, 612, 128) = 4
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 984, 612, 128 is 4.
Step 1: Since 984 > 612, we apply the division lemma to 984 and 612, to get
984 = 612 x 1 + 372
Step 2: Since the reminder 612 ≠ 0, we apply division lemma to 372 and 612, to get
612 = 372 x 1 + 240
Step 3: We consider the new divisor 372 and the new remainder 240, and apply the division lemma to get
372 = 240 x 1 + 132
We consider the new divisor 240 and the new remainder 132,and apply the division lemma to get
240 = 132 x 1 + 108
We consider the new divisor 132 and the new remainder 108,and apply the division lemma to get
132 = 108 x 1 + 24
We consider the new divisor 108 and the new remainder 24,and apply the division lemma to get
108 = 24 x 4 + 12
We consider the new divisor 24 and the new remainder 12,and apply the division lemma to get
24 = 12 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 984 and 612 is 12
Notice that 12 = HCF(24,12) = HCF(108,24) = HCF(132,108) = HCF(240,132) = HCF(372,240) = HCF(612,372) = HCF(984,612) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 128 > 12, we apply the division lemma to 128 and 12, to get
128 = 12 x 10 + 8
Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 8 and 12, to get
12 = 8 x 1 + 4
Step 3: We consider the new divisor 8 and the new remainder 4, and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 12 and 128 is 4
Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(128,12) .
Here are some samples of HCF using Euclid's Algorithm calculations.
