HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 278, 440, 480, 529 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 278, 440, 480, 529 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 278, 440, 480, 529 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 278, 440, 480, 529 is 1.
HCF(278, 440, 480, 529) = 1
HCF of 278, 440, 480, 529 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 278, 440, 480, 529 is 1.
Highest Common Factor of 278,440,480,529 is 1
Step 1: Since 440 > 278, we apply the division lemma to 440 and 278, to get
440 = 278 x 1 + 162
Step 2: Since the reminder 278 ≠ 0, we apply division lemma to 162 and 278, to get
278 = 162 x 1 + 116
Step 3: We consider the new divisor 162 and the new remainder 116, and apply the division lemma to get
162 = 116 x 1 + 46
We consider the new divisor 116 and the new remainder 46,and apply the division lemma to get
116 = 46 x 2 + 24
We consider the new divisor 46 and the new remainder 24,and apply the division lemma to get
46 = 24 x 1 + 22
We consider the new divisor 24 and the new remainder 22,and apply the division lemma to get
24 = 22 x 1 + 2
We consider the new divisor 22 and the new remainder 2,and apply the division lemma to get
22 = 2 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 278 and 440 is 2
Notice that 2 = HCF(22,2) = HCF(24,22) = HCF(46,24) = HCF(116,46) = HCF(162,116) = HCF(278,162) = HCF(440,278) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 480 > 2, we apply the division lemma to 480 and 2, to get
480 = 2 x 240 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 480 is 2
Notice that 2 = HCF(480,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 529 > 2, we apply the division lemma to 529 and 2, to get
529 = 2 x 264 + 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 529 is 1
Notice that 1 = HCF(2,1) = HCF(529,2) .
