HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 358, 782, 100, 729 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 358, 782, 100, 729 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 358, 782, 100, 729 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 358, 782, 100, 729 is 1.
HCF(358, 782, 100, 729) = 1
HCF of 358, 782, 100, 729 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 358, 782, 100, 729 is 1.
Highest Common Factor of 358,782,100,729 is 1
Step 1: Since 782 > 358, we apply the division lemma to 782 and 358, to get
782 = 358 x 2 + 66
Step 2: Since the reminder 358 ≠ 0, we apply division lemma to 66 and 358, to get
358 = 66 x 5 + 28
Step 3: We consider the new divisor 66 and the new remainder 28, and apply the division lemma to get
66 = 28 x 2 + 10
We consider the new divisor 28 and the new remainder 10,and apply the division lemma to get
28 = 10 x 2 + 8
We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get
10 = 8 x 1 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 358 and 782 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(28,10) = HCF(66,28) = HCF(358,66) = HCF(782,358) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 100 > 2, we apply the division lemma to 100 and 2, to get
100 = 2 x 50 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 100 is 2
Notice that 2 = HCF(100,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 729 > 2, we apply the division lemma to 729 and 2, to get
729 = 2 x 364 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 729 is 1
Notice that 1 = HCF(2,1) = HCF(729,2) .
