Given numbers are 130, 149, 87, 942
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(130, 149) = 19370
GCD(130, 149) = ( 130 x 149 ) / 19370
= 130 / 149
= 130
Step2:
LCM(1, 87) = 87
GCD(1, 87) = ( 1 x 87 ) / 87
= 1 / 87
= 1
Step3:
LCM(1, 942) = 942
GCD(1, 942) = ( 1 x 942 ) / 942
= 1 / 942
= 1
So, Greatest Common Divisor of 130, 149, 87, 942 is 1
