HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 585, 342, 778 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 585, 342, 778 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 585, 342, 778 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 585, 342, 778 is 1.
HCF(585, 342, 778) = 1
HCF of 585, 342, 778 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 585, 342, 778 is 1.
Highest Common Factor of 585,342,778 is 1
Step 1: Since 585 > 342, we apply the division lemma to 585 and 342, to get
585 = 342 x 1 + 243
Step 2: Since the reminder 342 ≠ 0, we apply division lemma to 243 and 342, to get
342 = 243 x 1 + 99
Step 3: We consider the new divisor 243 and the new remainder 99, and apply the division lemma to get
243 = 99 x 2 + 45
We consider the new divisor 99 and the new remainder 45,and apply the division lemma to get
99 = 45 x 2 + 9
We consider the new divisor 45 and the new remainder 9,and apply the division lemma to get
45 = 9 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 585 and 342 is 9
Notice that 9 = HCF(45,9) = HCF(99,45) = HCF(243,99) = HCF(342,243) = HCF(585,342) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 778 > 9, we apply the division lemma to 778 and 9, to get
778 = 9 x 86 + 4
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 4 and 9, to get
9 = 4 x 2 + 1
Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 9 and 778 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(778,9) .
