Given numbers are 987, 448, 348, 578
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 448) = 63168
GCD(987, 448) = ( 987 x 448 ) / 63168
= 987 / 448
= 987
Step2:
LCM(7, 348) = 2436
GCD(7, 348) = ( 7 x 348 ) / 2436
= 7 / 348
= 7
Step3:
LCM(1, 578) = 578
GCD(1, 578) = ( 1 x 578 ) / 578
= 1 / 578
= 1
So, Greatest Common Divisor of 987, 448, 348, 578 is 1
