The factor pairs of 840 are (840,1)(420,2)(280,3)(210,4)(168,5)(140,6)(120,7)(105,8)(84,10)(70,12)(60,14)(56,15)(42,20)(40,21)(35,24)(30,28)

To find the factors of 840, divide 840 by all numbers less than the square root of 840 that do not leave a remainder. This process gives factor pairs consisting of the divisor and the quotient. 840/1 = 840; factor pair is 1 and 840 840/2 = 420; factor pair is 2 and 420 840/3 = 280; factor pair is 3 and 280 840/4 = 210; factor pair is 4 and 210 840/5 = 168; factor pair is 5 and 168 840/6 = 140; factor pair is 6 and 140 840/7 = 120; factor pair is 7 and 120 840/8 = 105; factor pair is 8 and 105 840/10 = 84; factor pair is 10 and 84 840/12 = 70; factor pair is 12 and 70 840/14 = 60; factor pair is 14 and 60 840/15 = 56; factor pair is 15 and 56 840/20 = 42; factor pair is 20 and 42 840/21 = 40; factor pair is 21 and 40 840/24 = 35; factor pair is 24 and 35 840/28 = 30; factor pair is 28 and 30 The factor pairs can then be arranged in ascending numerical order. The factors of 840 are 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, and 840.

32 is not a factor of 840.

the factor pairs of 840 are (840,1)(420,2)(280,3)(210,4)(168,5)(140,6)(120,7)(105,8)(84,10)(70,12)(60,14)(56,15)(42,20)(40,21)(35,24)(30,28)

actually 7 is a factor of 840, because when you divide 7 into 840 you get 120 with no remainders therefore making it a factor of 840.🤡

(1, 840) (2, 420) (3, 280) (4, 210) (5, 168) (6, 140) (7, 120) (8, 105)

Stings with four factor that make 840

Since 280 is a factor of 840, it is automatically the GCF.

21

Yes

The GCF of 320 and 840 is 40.

Yes. Factor pairs are always repeated across pairs since factor pairs are certain kinds of pairs.

Factors produce numbers. To get 840, use these factor pairs: (840,1)(420,2)(280,3)(210,4)(168,5)(140,6)(120,7)(105,8)(84,10)(70,12)(60,14)(56,15)(42,20)(40,21)(35,24)(30,28)

Multiples are numbers that a number (840 in this case) is a factor of.Multiples of 840: 1680, 2520, 3360, and so on.
