HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 715, 429, 646, 562 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 715, 429, 646, 562 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 715, 429, 646, 562 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 715, 429, 646, 562 is 1.
HCF(715, 429, 646, 562) = 1
HCF of 715, 429, 646, 562 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 715, 429, 646, 562 is 1.
Highest Common Factor of 715,429,646,562 is 1
Step 1: Since 715 > 429, we apply the division lemma to 715 and 429, to get
715 = 429 x 1 + 286
Step 2: Since the reminder 429 ≠ 0, we apply division lemma to 286 and 429, to get
429 = 286 x 1 + 143
Step 3: We consider the new divisor 286 and the new remainder 143, and apply the division lemma to get
286 = 143 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 143, the HCF of 715 and 429 is 143
Notice that 143 = HCF(286,143) = HCF(429,286) = HCF(715,429) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 646 > 143, we apply the division lemma to 646 and 143, to get
646 = 143 x 4 + 74
Step 2: Since the reminder 143 ≠ 0, we apply division lemma to 74 and 143, to get
143 = 74 x 1 + 69
Step 3: We consider the new divisor 74 and the new remainder 69, and apply the division lemma to get
74 = 69 x 1 + 5
We consider the new divisor 69 and the new remainder 5,and apply the division lemma to get
69 = 5 x 13 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
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 143 and 646 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(69,5) = HCF(74,69) = HCF(143,74) = HCF(646,143) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 562 > 1, we apply the division lemma to 562 and 1, to get
562 = 1 x 562 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 562 is 1
Notice that 1 = HCF(562,1) .
