HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 520, 153, 647, 727 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 520, 153, 647, 727 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 520, 153, 647, 727 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 520, 153, 647, 727 is 1.
HCF(520, 153, 647, 727) = 1
HCF of 520, 153, 647, 727 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 520, 153, 647, 727 is 1.
Highest Common Factor of 520,153,647,727 is 1
Step 1: Since 520 > 153, we apply the division lemma to 520 and 153, to get
520 = 153 x 3 + 61
Step 2: Since the reminder 153 ≠ 0, we apply division lemma to 61 and 153, to get
153 = 61 x 2 + 31
Step 3: We consider the new divisor 61 and the new remainder 31, and apply the division lemma to get
61 = 31 x 1 + 30
We consider the new divisor 31 and the new remainder 30,and apply the division lemma to get
31 = 30 x 1 + 1
We consider the new divisor 30 and the new remainder 1,and apply the division lemma to get
30 = 1 x 30 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 520 and 153 is 1
Notice that 1 = HCF(30,1) = HCF(31,30) = HCF(61,31) = HCF(153,61) = HCF(520,153) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 647 > 1, we apply the division lemma to 647 and 1, to get
647 = 1 x 647 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 647 is 1
Notice that 1 = HCF(647,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 727 > 1, we apply the division lemma to 727 and 1, to get
727 = 1 x 727 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 727 is 1
Notice that 1 = HCF(727,1) .
