2 * 2 * 7 * 7 * 7 = 1372
1372 = 2*2*7*7*7 1372 has the factors: 1, 2, 4, 7, 14, 28, 49, 98, 196, 343, 686, 1372 The only prime factors are 2 and 7.
2.1952
1, 2, 4, 7, 14, 28, 49, 98, 196, 343, 686, and 1372
1372 = 2*686 = 2^2*343 = 2^2*7^3 So the factors are 1, 2, 4, 7, 14, 28, 49, 98, 196, 343, 686 and 1372 itself.
1 and 1372 2 and 686 4 and 343 7 and 196 14 and 98 28 and 49 That's it
1371+1=1372
* The answer is 1386 * 7x4=28 * 28x7=196 * 196x7=1372 * 7x2=14 * 1372+14=1386
1 mile = 1.609 km 1372 km = 1372/1.609 miles
Four sevenths of 49 is (49÷7)×4 and the answer is 28
They are: 1372+1372 = 2744
Volume sphere = 4/3 πr³ = 4/3 π 7³ = 1372π/3 Volume cylinder = πr²h = 1372π/3 → r²h = 1372/3 So as long as the radius of the cylinder is related to its height by: radius = √(1372 / (3×height)) or height = 1372 / (3×radius²) You can have a cylinder of almost any size you want. Example sizes: radius 1, height 1372/3 radius 7, height 28/3 height 7, radius 14/√3 height 28/3, radius 7 height 49, radius √(28/3)
