Given numbers are 428, 142, 670, 133
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 142) = 30388
GCD(428, 142) = ( 428 x 142 ) / 30388
= 428 / 142
= 428
Step2:
LCM(2, 670) = 670
GCD(2, 670) = ( 2 x 670 ) / 670
= 2 / 670
= 2
Step3:
LCM(2, 133) = 266
GCD(2, 133) = ( 2 x 133 ) / 266
= 2 / 133
= 2
So, Greatest Common Divisor of 428, 142, 670, 133 is 1
