HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 242, 617, 521, 570 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 242, 617, 521, 570 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 242, 617, 521, 570 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 242, 617, 521, 570 is 1.
HCF(242, 617, 521, 570) = 1
HCF of 242, 617, 521, 570 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 242, 617, 521, 570 is 1.
Highest Common Factor of 242,617,521,570 is 1
Step 1: Since 617 > 242, we apply the division lemma to 617 and 242, to get
617 = 242 x 2 + 133
Step 2: Since the reminder 242 ≠ 0, we apply division lemma to 133 and 242, to get
242 = 133 x 1 + 109
Step 3: We consider the new divisor 133 and the new remainder 109, and apply the division lemma to get
133 = 109 x 1 + 24
We consider the new divisor 109 and the new remainder 24,and apply the division lemma to get
109 = 24 x 4 + 13
We consider the new divisor 24 and the new remainder 13,and apply the division lemma to get
24 = 13 x 1 + 11
We consider the new divisor 13 and the new remainder 11,and apply the division lemma to get
13 = 11 x 1 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 1
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 242 and 617 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(24,13) = HCF(109,24) = HCF(133,109) = HCF(242,133) = HCF(617,242) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 521 > 1, we apply the division lemma to 521 and 1, to get
521 = 1 x 521 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 521 is 1
Notice that 1 = HCF(521,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 570 > 1, we apply the division lemma to 570 and 1, to get
570 = 1 x 570 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 570 is 1
Notice that 1 = HCF(570,1) .
