HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 437, 320, 648, 213 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 437, 320, 648, 213 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 437, 320, 648, 213 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 437, 320, 648, 213 is 1.

HCF(437, 320, 648, 213) = 1

Highest Common Factor of 437,320,648,213 using Euclid's algorithm

Highest Common Factor of 437,320,648,213 is 1

Step 1: Since 437 > 320, we apply the division lemma to 437 and 320, to get

437 = 320 x 1 + 117

Step 2: Since the reminder 320 ≠ 0, we apply division lemma to 117 and 320, to get

320 = 117 x 2 + 86

Step 3: We consider the new divisor 117 and the new remainder 86, and apply the division lemma to get

117 = 86 x 1 + 31

We consider the new divisor 86 and the new remainder 31,and apply the division lemma to get

86 = 31 x 2 + 24

We consider the new divisor 31 and the new remainder 24,and apply the division lemma to get

31 = 24 x 1 + 7

We consider the new divisor 24 and the new remainder 7,and apply the division lemma to get

24 = 7 x 3 + 3

We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get

7 = 3 x 2 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 437 and 320 is 1

Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(24,7) = HCF(31,24) = HCF(86,31) = HCF(117,86) = HCF(320,117) = HCF(437,320) .


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

Step 1: Since 648 > 1, we apply the division lemma to 648 and 1, to get

648 = 1 x 648 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 648 is 1

Notice that 1 = HCF(648,1) .


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

Step 1: Since 213 > 1, we apply the division lemma to 213 and 1, to get

213 = 1 x 213 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 213 is 1

Notice that 1 = HCF(213,1) .
