Given numbers are 120, 342, 142, 913
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(120, 342) = 6840
GCD(120, 342) = ( 120 x 342 ) / 6840
= 120 / 342
= 120
Step2:
LCM(6, 142) = 426
GCD(6, 142) = ( 6 x 142 ) / 426
= 6 / 142
= 6
Step3:
LCM(2, 913) = 1826
GCD(2, 913) = ( 2 x 913 ) / 1826
= 2 / 913
= 2
So, Greatest Common Divisor of 120, 342, 142, 913 is 1
