HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 68, 509, 616, 255 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 68, 509, 616, 255 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 68, 509, 616, 255 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 68, 509, 616, 255 is 1.
HCF(68, 509, 616, 255) = 1
HCF of 68, 509, 616, 255 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 68, 509, 616, 255 is 1.
Highest Common Factor of 68,509,616,255 is 1
Step 1: Since 509 > 68, we apply the division lemma to 509 and 68, to get
509 = 68 x 7 + 33
Step 2: Since the reminder 68 ≠ 0, we apply division lemma to 33 and 68, to get
68 = 33 x 2 + 2
Step 3: We consider the new divisor 33 and the new remainder 2, and apply the division lemma to get
33 = 2 x 16 + 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 68 and 509 is 1
Notice that 1 = HCF(2,1) = HCF(33,2) = HCF(68,33) = HCF(509,68) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 616 > 1, we apply the division lemma to 616 and 1, to get
616 = 1 x 616 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 616 is 1
Notice that 1 = HCF(616,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 255 > 1, we apply the division lemma to 255 and 1, to get
255 = 1 x 255 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 255 is 1
Notice that 1 = HCF(255,1) .
