HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 119, 561, 155 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 119, 561, 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 119, 561, 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 119, 561, 155 is 1.
HCF(119, 561, 155) = 1
HCF of 119, 561, 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 119, 561, 155 is 1.
Highest Common Factor of 119,561,155 is 1
Step 1: Since 561 > 119, we apply the division lemma to 561 and 119, to get
561 = 119 x 4 + 85
Step 2: Since the reminder 119 ≠ 0, we apply division lemma to 85 and 119, to get
119 = 85 x 1 + 34
Step 3: We consider the new divisor 85 and the new remainder 34, and apply the division lemma to get
85 = 34 x 2 + 17
We consider the new divisor 34 and the new remainder 17, and apply the division lemma to get
34 = 17 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 119 and 561 is 17
Notice that 17 = HCF(34,17) = HCF(85,34) = HCF(119,85) = HCF(561,119) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 155 > 17, we apply the division lemma to 155 and 17, to get
155 = 17 x 9 + 2
Step 2: Since the reminder 17 ≠ 0, we apply division lemma to 2 and 17, to get
17 = 2 x 8 + 1
Step 3: 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 17 and 155 is 1
Notice that 1 = HCF(2,1) = HCF(17,2) = HCF(155,17) .
