GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(153, 603) = 10251
GCD(153, 603) = ( 153 x 603 ) / 10251
= 153 / 603
= 153
Step2:
LCM(9, 997) = 8973
GCD(9, 997) = ( 9 x 997 ) / 8973
= 9 / 997
= 9
Step3:
LCM(1, 768) = 768
GCD(1, 768) = ( 1 x 768 ) / 768
= 1 / 768
= 1
So, Greatest Common Divisor of 153, 603, 997, 768 is 1
