HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 210, 105, 755, 495 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 210, 105, 755, 495 is 5 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 210, 105, 755, 495 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 210, 105, 755, 495 is 5.
HCF(210, 105, 755, 495) = 5
HCF of 210, 105, 755, 495 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 210, 105, 755, 495 is 5.
Highest Common Factor of 210,105,755,495 is 5
Step 1: Since 210 > 105, we apply the division lemma to 210 and 105, to get
210 = 105 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 105, the HCF of 210 and 105 is 105
Notice that 105 = HCF(210,105) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 755 > 105, we apply the division lemma to 755 and 105, to get
755 = 105 x 7 + 20
Step 2: Since the reminder 105 ≠ 0, we apply division lemma to 20 and 105, to get
105 = 20 x 5 + 5
Step 3: We consider the new divisor 20 and the new remainder 5, and apply the division lemma to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 105 and 755 is 5
Notice that 5 = HCF(20,5) = HCF(105,20) = HCF(755,105) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 495 > 5, we apply the division lemma to 495 and 5, to get
495 = 5 x 99 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 495 is 5
Notice that 5 = HCF(495,5) .
