HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 282, 387, 920, 540 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 282, 387, 920, 540 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 282, 387, 920, 540 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 282, 387, 920, 540 is 1.
HCF(282, 387, 920, 540) = 1
HCF of 282, 387, 920, 540 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 282, 387, 920, 540 is 1.
Highest Common Factor of 282,387,920,540 is 1
Step 1: Since 387 > 282, we apply the division lemma to 387 and 282, to get
387 = 282 x 1 + 105
Step 2: Since the reminder 282 ≠ 0, we apply division lemma to 105 and 282, to get
282 = 105 x 2 + 72
Step 3: We consider the new divisor 105 and the new remainder 72, and apply the division lemma to get
105 = 72 x 1 + 33
We consider the new divisor 72 and the new remainder 33,and apply the division lemma to get
72 = 33 x 2 + 6
We consider the new divisor 33 and the new remainder 6,and apply the division lemma to get
33 = 6 x 5 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 282 and 387 is 3
Notice that 3 = HCF(6,3) = HCF(33,6) = HCF(72,33) = HCF(105,72) = HCF(282,105) = HCF(387,282) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 920 > 3, we apply the division lemma to 920 and 3, to get
920 = 3 x 306 + 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 920 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(920,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 540 > 1, we apply the division lemma to 540 and 1, to get
540 = 1 x 540 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 540 is 1
Notice that 1 = HCF(540,1) .
