Highest Common Factor of 115, 745, 465, 640 using Euclid's algorithm

HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 115, 745, 465, 640 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 115, 745, 465, 640 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 115, 745, 465, 640 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 115, 745, 465, 640 is 5.

HCF(115, 745, 465, 640) = 5

HCF of 115, 745, 465, 640 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 115, 745, 465, 640 is 5.

Highest Common Factor of 115,745,465,640 using Euclid's algorithm

Step 1: Since 745 > 115, we apply the division lemma to 745 and 115, to get

745 = 115 x 6 + 55

Step 2: Since the reminder 115 ≠ 0, we apply division lemma to 55 and 115, to get

115 = 55 x 2 + 5

Step 3: We consider the new divisor 55 and the new remainder 5, and apply the division lemma to get

55 = 5 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 115 and 745 is 5

Notice that 5 = HCF(55,5) = HCF(115,55) = HCF(745,115) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 465 > 5, we apply the division lemma to 465 and 5, to get

465 = 5 x 93 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 465 is 5

Notice that 5 = HCF(465,5) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 640 > 5, we apply the division lemma to 640 and 5, to get

640 = 5 x 128 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 640 is 5

Notice that 5 = HCF(640,5) .
