HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 415, 220, 615, 90 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 415, 220, 615, 90 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 415, 220, 615, 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 415, 220, 615, 90 is 5.

HCF(415, 220, 615, 90) = 5

Highest Common Factor of 415,220,615,90 using Euclid's algorithm

Highest Common Factor of 415,220,615,90 is 5

Step 1: Since 415 > 220, we apply the division lemma to 415 and 220, to get

415 = 220 x 1 + 195

Step 2: Since the reminder 220 ≠ 0, we apply division lemma to 195 and 220, to get

220 = 195 x 1 + 25

Step 3: We consider the new divisor 195 and the new remainder 25, and apply the division lemma to get

195 = 25 x 7 + 20

We consider the new divisor 25 and the new remainder 20,and apply the division lemma to get

25 = 20 x 1 + 5

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 415 and 220 is 5

Notice that 5 = HCF(20,5) = HCF(25,20) = HCF(195,25) = HCF(220,195) = HCF(415,220) .


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

Step 1: Since 615 > 5, we apply the division lemma to 615 and 5, to get

615 = 5 x 123 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 615 is 5

Notice that 5 = HCF(615,5) .


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

Step 1: Since 90 > 5, we apply the division lemma to 90 and 5, to get

90 = 5 x 18 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 90 is 5

Notice that 5 = HCF(90,5) .
