Given numbers are 298, 139, 807, 342
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(298, 139) = 41422
GCD(298, 139) = ( 298 x 139 ) / 41422
= 298 / 139
= 298
Step2:
LCM(1, 807) = 807
GCD(1, 807) = ( 1 x 807 ) / 807
= 1 / 807
= 1
Step3:
LCM(1, 342) = 342
GCD(1, 342) = ( 1 x 342 ) / 342
= 1 / 342
= 1
So, Greatest Common Divisor of 298, 139, 807, 342 is 1
