HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 273, 153, 368, 354 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 273, 153, 368, 354 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 273, 153, 368, 354 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 273, 153, 368, 354 is 1.
HCF(273, 153, 368, 354) = 1
HCF of 273, 153, 368, 354 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 273, 153, 368, 354 is 1.
Highest Common Factor of 273,153,368,354 is 1
Step 1: Since 273 > 153, we apply the division lemma to 273 and 153, to get
273 = 153 x 1 + 120
Step 2: Since the reminder 153 ≠ 0, we apply division lemma to 120 and 153, to get
153 = 120 x 1 + 33
Step 3: We consider the new divisor 120 and the new remainder 33, and apply the division lemma to get
120 = 33 x 3 + 21
We consider the new divisor 33 and the new remainder 21,and apply the division lemma to get
33 = 21 x 1 + 12
We consider the new divisor 21 and the new remainder 12,and apply the division lemma to get
21 = 12 x 1 + 9
We consider the new divisor 12 and the new remainder 9,and apply the division lemma to get
12 = 9 x 1 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 273 and 153 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(21,12) = HCF(33,21) = HCF(120,33) = HCF(153,120) = HCF(273,153) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 368 > 3, we apply the division lemma to 368 and 3, to get
368 = 3 x 122 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 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 3 and 368 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(368,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 354 > 1, we apply the division lemma to 354 and 1, to get
354 = 1 x 354 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 354 is 1
Notice that 1 = HCF(354,1) .
