HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 259, 666, 155 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 259, 666, 155 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 259, 666, 155 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 259, 666, 155 is 1.
HCF(259, 666, 155) = 1
HCF of 259, 666, 155 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 259, 666, 155 is 1.
Highest Common Factor of 259,666,155 is 1
Step 1: Since 666 > 259, we apply the division lemma to 666 and 259, to get
666 = 259 x 2 + 148
Step 2: Since the reminder 259 ≠ 0, we apply division lemma to 148 and 259, to get
259 = 148 x 1 + 111
Step 3: We consider the new divisor 148 and the new remainder 111, and apply the division lemma to get
148 = 111 x 1 + 37
We consider the new divisor 111 and the new remainder 37, and apply the division lemma to get
111 = 37 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 37, the HCF of 259 and 666 is 37
Notice that 37 = HCF(111,37) = HCF(148,111) = HCF(259,148) = HCF(666,259) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 155 > 37, we apply the division lemma to 155 and 37, to get
155 = 37 x 4 + 7
Step 2: Since the reminder 37 ≠ 0, we apply division lemma to 7 and 37, to get
37 = 7 x 5 + 2
Step 3: We consider the new divisor 7 and the new remainder 2, and apply the division lemma to get
7 = 2 x 3 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 37 and 155 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(37,7) = HCF(155,37) .
