Given numbers are 987, 109, 782, 603
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 109) = 107583
GCD(987, 109) = ( 987 x 109 ) / 107583
= 987 / 109
= 987
Step2:
LCM(1, 782) = 782
GCD(1, 782) = ( 1 x 782 ) / 782
= 1 / 782
= 1
Step3:
LCM(1, 603) = 603
GCD(1, 603) = ( 1 x 603 ) / 603
= 1 / 603
= 1
So, Greatest Common Divisor of 987, 109, 782, 603 is 1
