GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(578, 427) = 246806
GCD(578, 427) = ( 578 x 427 ) / 246806
= 578 / 427
= 578
Step2:
LCM(1, 987) = 987
GCD(1, 987) = ( 1 x 987 ) / 987
= 1 / 987
= 1
Step3:
LCM(1, 356) = 356
GCD(1, 356) = ( 1 x 356 ) / 356
= 1 / 356
= 1
So, Greatest Common Divisor of 578, 427, 987, 356 is 1
