HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1365, 4225, 94685 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 1365, 4225, 94685 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 1365, 4225, 94685 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 1365, 4225, 94685 is 5.
HCF(1365, 4225, 94685) = 5
HCF of 1365, 4225, 94685 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1365, 4225, 94685 is 5.
Highest Common Factor of 1365,4225,94685 is 5
Step 1: Since 4225 > 1365, we apply the division lemma to 4225 and 1365, to get
4225 = 1365 x 3 + 130
Step 2: Since the reminder 1365 ≠ 0, we apply division lemma to 130 and 1365, to get
1365 = 130 x 10 + 65
Step 3: We consider the new divisor 130 and the new remainder 65, and apply the division lemma to get
130 = 65 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 65, the HCF of 1365 and 4225 is 65
Notice that 65 = HCF(130,65) = HCF(1365,130) = HCF(4225,1365) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 94685 > 65, we apply the division lemma to 94685 and 65, to get
94685 = 65 x 1456 + 45
Step 2: Since the reminder 65 ≠ 0, we apply division lemma to 45 and 65, to get
65 = 45 x 1 + 20
Step 3: We consider the new divisor 45 and the new remainder 20, and apply the division lemma to get
45 = 20 x 2 + 5
We consider the new divisor 20 and the new remainder 5, and apply the division lemma to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 65 and 94685 is 5
Notice that 5 = HCF(20,5) = HCF(45,20) = HCF(65,45) = HCF(94685,65) .
