GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 368) = 61456
GCD(668, 368) = ( 668 x 368 ) / 61456
= 668 / 368
= 668
Step2:
LCM(4, 275) = 1100
GCD(4, 275) = ( 4 x 275 ) / 1100
= 4 / 275
= 4
Step3:
LCM(1, 142) = 142
GCD(1, 142) = ( 1 x 142 ) / 142
= 1 / 142
= 1
So, Greatest Common Divisor of 668, 368, 275, 142 is 1
