HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 146, 554, 559, 72 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 146, 554, 559, 72 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 146, 554, 559, 72 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 146, 554, 559, 72 is 1.
HCF(146, 554, 559, 72) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 146, 554, 559, 72 is 1.
Step 1: Since 554 > 146, we apply the division lemma to 554 and 146, to get
554 = 146 x 3 + 116
Step 2: Since the reminder 146 ≠ 0, we apply division lemma to 116 and 146, to get
146 = 116 x 1 + 30
Step 3: We consider the new divisor 116 and the new remainder 30, and apply the division lemma to get
116 = 30 x 3 + 26
We consider the new divisor 30 and the new remainder 26,and apply the division lemma to get
30 = 26 x 1 + 4
We consider the new divisor 26 and the new remainder 4,and apply the division lemma to get
26 = 4 x 6 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 146 and 554 is 2
Notice that 2 = HCF(4,2) = HCF(26,4) = HCF(30,26) = HCF(116,30) = HCF(146,116) = HCF(554,146) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 559 > 2, we apply the division lemma to 559 and 2, to get
559 = 2 x 279 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 559 is 1
Notice that 1 = HCF(2,1) = HCF(559,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 72 > 1, we apply the division lemma to 72 and 1, to get
72 = 1 x 72 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 72 is 1
Notice that 1 = HCF(72,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
