HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 15, 282, 166, 789 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 15, 282, 166, 789 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 15, 282, 166, 789 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 15, 282, 166, 789 is 1.
HCF(15, 282, 166, 789) = 1
HCF of 15, 282, 166, 789 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 15, 282, 166, 789 is 1.
Highest Common Factor of 15,282,166,789 is 1
Step 1: Since 282 > 15, we apply the division lemma to 282 and 15, to get
282 = 15 x 18 + 12
Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 12 and 15, to get
15 = 12 x 1 + 3
Step 3: We consider the new divisor 12 and the new remainder 3, and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 15 and 282 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(282,15) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 166 > 3, we apply the division lemma to 166 and 3, to get
166 = 3 x 55 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 166 is 1
Notice that 1 = HCF(3,1) = HCF(166,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 789 > 1, we apply the division lemma to 789 and 1, to get
789 = 1 x 789 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 789 is 1
Notice that 1 = HCF(789,1) .
