HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 918, 486, 193 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 918, 486, 193 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 918, 486, 193 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 918, 486, 193 is 1.
HCF(918, 486, 193) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 918, 486, 193 is 1.
Step 1: Since 918 > 486, we apply the division lemma to 918 and 486, to get
918 = 486 x 1 + 432
Step 2: Since the reminder 486 ≠ 0, we apply division lemma to 432 and 486, to get
486 = 432 x 1 + 54
Step 3: We consider the new divisor 432 and the new remainder 54, and apply the division lemma to get
432 = 54 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 54, the HCF of 918 and 486 is 54
Notice that 54 = HCF(432,54) = HCF(486,432) = HCF(918,486) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 193 > 54, we apply the division lemma to 193 and 54, to get
193 = 54 x 3 + 31
Step 2: Since the reminder 54 ≠ 0, we apply division lemma to 31 and 54, to get
54 = 31 x 1 + 23
Step 3: We consider the new divisor 31 and the new remainder 23, and apply the division lemma to get
31 = 23 x 1 + 8
We consider the new divisor 23 and the new remainder 8,and apply the division lemma to get
23 = 8 x 2 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 54 and 193 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(23,8) = HCF(31,23) = HCF(54,31) = HCF(193,54) .
Here are some samples of HCF using Euclid's Algorithm calculations.
