если надо кратное 5-ти
let value = 100;
let count = 4;
const multiplier = 5;
value /= multiplier;
const numbers = [];
while (count > 1)
{
const number = ~~(Math.random() * (value - count)) + 1;
value -= number;
numbers.push(number * multiplier);
count--;
}
numbers.push(value * multiplier);
let sum = 0;
numbers.map(number => sum += number);
console.log(numbers);
console.log(sum);
// [ 55, 10, 20, 15 ]
// 100
