HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 516, 759, 393, 90 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 516, 759, 393, 90 is 3 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 516, 759, 393, 90 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 516, 759, 393, 90 is 3.
HCF(516, 759, 393, 90) = 3
HCF of 516, 759, 393, 90 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 516, 759, 393, 90 is 3.
Highest Common Factor of 516,759,393,90 is 3
Step 1: Since 759 > 516, we apply the division lemma to 759 and 516, to get
759 = 516 x 1 + 243
Step 2: Since the reminder 516 ≠ 0, we apply division lemma to 243 and 516, to get
516 = 243 x 2 + 30
Step 3: We consider the new divisor 243 and the new remainder 30, and apply the division lemma to get
243 = 30 x 8 + 3
We consider the new divisor 30 and the new remainder 3, and apply the division lemma to get
30 = 3 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 516 and 759 is 3
Notice that 3 = HCF(30,3) = HCF(243,30) = HCF(516,243) = HCF(759,516) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 393 > 3, we apply the division lemma to 393 and 3, to get
393 = 3 x 131 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 393 is 3
Notice that 3 = HCF(393,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 90 > 3, we apply the division lemma to 90 and 3, to get
90 = 3 x 30 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 90 is 3
Notice that 3 = HCF(90,3) .
