HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 970, 815, 650, 55 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 970, 815, 650, 55 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 970, 815, 650, 55 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 970, 815, 650, 55 is 5.

HCF(970, 815, 650, 55) = 5

Highest common factor (HCF) of 970, 815, 650, 55 is 5.

Highest Common Factor of 970,815,650,55 using Euclid's algorithm

Highest Common Factor of 970,815,650,55 is 5

Step 1: Since 970 > 815, we apply the division lemma to 970 and 815, to get

970 = 815 x 1 + 155

Step 2: Since the reminder 815 ≠ 0, we apply division lemma to 155 and 815, to get

815 = 155 x 5 + 40

Step 3: We consider the new divisor 155 and the new remainder 40, and apply the division lemma to get

155 = 40 x 3 + 35

We consider the new divisor 40 and the new remainder 35,and apply the division lemma to get

40 = 35 x 1 + 5

We consider the new divisor 35 and the new remainder 5,and apply the division lemma to get

35 = 5 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 970 and 815 is 5

Notice that 5 = HCF(35,5) = HCF(40,35) = HCF(155,40) = HCF(815,155) = HCF(970,815) .


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

Step 1: Since 650 > 5, we apply the division lemma to 650 and 5, to get

650 = 5 x 130 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 650 is 5

Notice that 5 = HCF(650,5) .


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

Step 1: Since 55 > 5, we apply the division lemma to 55 and 5, 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 5 and 55 is 5

Notice that 5 = HCF(55,5) .
