HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 428, 783, 360 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 428, 783, 360 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 428, 783, 360 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 428, 783, 360 is 1.

HCF(428, 783, 360) = 1

Highest common factor (HCF) of 428, 783, 360 is 1.

Highest Common Factor of 428,783,360 using Euclid's algorithm

Highest Common Factor of 428,783,360 is 1

Step 1: Since 783 > 428, we apply the division lemma to 783 and 428, to get

783 = 428 x 1 + 355

Step 2: Since the reminder 428 ≠ 0, we apply division lemma to 355 and 428, to get

428 = 355 x 1 + 73

Step 3: We consider the new divisor 355 and the new remainder 73, and apply the division lemma to get

355 = 73 x 4 + 63

We consider the new divisor 73 and the new remainder 63,and apply the division lemma to get

73 = 63 x 1 + 10

We consider the new divisor 63 and the new remainder 10,and apply the division lemma to get

63 = 10 x 6 + 3

We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get

10 = 3 x 3 + 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 428 and 783 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(63,10) = HCF(73,63) = HCF(355,73) = HCF(428,355) = HCF(783,428) .

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

Step 1: Since 360 > 1, we apply the division lemma to 360 and 1, to get

360 = 1 x 360 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 360 is 1

Notice that 1 = HCF(360,1) .
