HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 972, 273, 394, 582 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 972, 273, 394, 582 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 972, 273, 394, 582 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 972, 273, 394, 582 is 1.
HCF(972, 273, 394, 582) = 1
HCF of 972, 273, 394, 582 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 972, 273, 394, 582 is 1.
Highest Common Factor of 972,273,394,582 is 1
Step 1: Since 972 > 273, we apply the division lemma to 972 and 273, to get
972 = 273 x 3 + 153
Step 2: Since the reminder 273 ≠ 0, we apply division lemma to 153 and 273, to get
273 = 153 x 1 + 120
Step 3: We consider the new divisor 153 and the new remainder 120, and apply the division lemma to get
153 = 120 x 1 + 33
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 972 and 273 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) = HCF(972,273) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 394 > 3, we apply the division lemma to 394 and 3, to get
394 = 3 x 131 + 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 394 is 1
Notice that 1 = HCF(3,1) = HCF(394,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 582 > 1, we apply the division lemma to 582 and 1, to get
582 = 1 x 582 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 582 is 1
Notice that 1 = HCF(582,1) .
