HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 435, 207, 85, 650 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 435, 207, 85, 650 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 435, 207, 85, 650 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 435, 207, 85, 650 is 1.

HCF(435, 207, 85, 650) = 1

Highest common factor (HCF) of 435, 207, 85, 650 is 1.

Highest Common Factor of 435,207,85,650 using Euclid's algorithm

Highest Common Factor of 435,207,85,650 is 1

Step 1: Since 435 > 207, we apply the division lemma to 435 and 207, to get

435 = 207 x 2 + 21

Step 2: Since the reminder 207 ≠ 0, we apply division lemma to 21 and 207, to get

207 = 21 x 9 + 18

Step 3: We consider the new divisor 21 and the new remainder 18, and apply the division lemma to get

21 = 18 x 1 + 3

We consider the new divisor 18 and the new remainder 3, and apply the division lemma to get

18 = 3 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 435 and 207 is 3

Notice that 3 = HCF(18,3) = HCF(21,18) = HCF(207,21) = HCF(435,207) .


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

Step 1: Since 85 > 3, we apply the division lemma to 85 and 3, to get

85 = 3 x 28 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 85 is 1

Notice that 1 = HCF(3,1) = HCF(85,3) .


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

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

650 = 1 x 650 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 650 is 1

Notice that 1 = HCF(650,1) .
