GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(743, 987) = 733341
GCD(743, 987) = ( 743 x 987 ) / 733341
= 743 / 987
= 743
Step2:
LCM(1, 78) = 78
GCD(1, 78) = ( 1 x 78 ) / 78
= 1 / 78
= 1
Step3:
LCM(1, 440) = 440
GCD(1, 440) = ( 1 x 440 ) / 440
= 1 / 440
= 1
So, Greatest Common Divisor of 743, 987, 78, 440 is 1
