Given numbers are 298, 356, 851, 140
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(298, 356) = 53044
GCD(298, 356) = ( 298 x 356 ) / 53044
= 298 / 356
= 298
Step2:
LCM(2, 851) = 1702
GCD(2, 851) = ( 2 x 851 ) / 1702
= 2 / 851
= 2
Step3:
LCM(1, 140) = 140
GCD(1, 140) = ( 1 x 140 ) / 140
= 1 / 140
= 1
So, Greatest Common Divisor of 298, 356, 851, 140 is 1
