HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 564, 215, 282, 70 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 564, 215, 282, 70 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 564, 215, 282, 70 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 564, 215, 282, 70 is 1.
HCF(564, 215, 282, 70) = 1
HCF of 564, 215, 282, 70 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 564, 215, 282, 70 is 1.
Highest Common Factor of 564,215,282,70 is 1
Step 1: Since 564 > 215, we apply the division lemma to 564 and 215, to get
564 = 215 x 2 + 134
Step 2: Since the reminder 215 ≠ 0, we apply division lemma to 134 and 215, to get
215 = 134 x 1 + 81
Step 3: We consider the new divisor 134 and the new remainder 81, and apply the division lemma to get
134 = 81 x 1 + 53
We consider the new divisor 81 and the new remainder 53,and apply the division lemma to get
81 = 53 x 1 + 28
We consider the new divisor 53 and the new remainder 28,and apply the division lemma to get
53 = 28 x 1 + 25
We consider the new divisor 28 and the new remainder 25,and apply the division lemma to get
28 = 25 x 1 + 3
We consider the new divisor 25 and the new remainder 3,and apply the division lemma to get
25 = 3 x 8 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 564 and 215 is 1
Notice that 1 = HCF(3,1) = HCF(25,3) = HCF(28,25) = HCF(53,28) = HCF(81,53) = HCF(134,81) = HCF(215,134) = HCF(564,215) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 282 > 1, we apply the division lemma to 282 and 1, to get
282 = 1 x 282 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 282 is 1
Notice that 1 = HCF(282,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 70 > 1, we apply the division lemma to 70 and 1, to get
70 = 1 x 70 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 70 is 1
Notice that 1 = HCF(70,1) .
