Given numbers are 987, 708, 205, 490
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 708) = 232932
GCD(987, 708) = ( 987 x 708 ) / 232932
= 987 / 708
= 987
Step2:
LCM(3, 205) = 615
GCD(3, 205) = ( 3 x 205 ) / 615
= 3 / 205
= 3
Step3:
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
= 1 / 490
= 1
So, Greatest Common Divisor of 987, 708, 205, 490 is 1
