HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 370, 845, 195, 780 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 370, 845, 195, 780 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 370, 845, 195, 780 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 370, 845, 195, 780 is 5.

HCF(370, 845, 195, 780) = 5

HCF of 370, 845, 195, 780 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 370, 845, 195, 780 is 5.

Highest Common Factor of 370,845,195,780 using Euclid's algorithm

Highest Common Factor of 370,845,195,780 is 5

Step 1: Since 845 > 370, we apply the division lemma to 845 and 370, to get

845 = 370 x 2 + 105

Step 2: Since the reminder 370 ≠ 0, we apply division lemma to 105 and 370, to get

370 = 105 x 3 + 55

Step 3: We consider the new divisor 105 and the new remainder 55, and apply the division lemma to get

105 = 55 x 1 + 50

We consider the new divisor 55 and the new remainder 50,and apply the division lemma to get

55 = 50 x 1 + 5

We consider the new divisor 50 and the new remainder 5,and apply the division lemma to get

50 = 5 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 370 and 845 is 5

Notice that 5 = HCF(50,5) = HCF(55,50) = HCF(105,55) = HCF(370,105) = HCF(845,370) .


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

Step 1: Since 195 > 5, we apply the division lemma to 195 and 5, to get

195 = 5 x 39 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 195 is 5

Notice that 5 = HCF(195,5) .


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

Step 1: Since 780 > 5, we apply the division lemma to 780 and 5, to get

780 = 5 x 156 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 780 is 5

Notice that 5 = HCF(780,5) .
