Given numbers are 670, 138, 515, 140
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(670, 138) = 46230
GCD(670, 138) = ( 670 x 138 ) / 46230
= 670 / 138
= 670
Step2:
LCM(2, 515) = 1030
GCD(2, 515) = ( 2 x 515 ) / 1030
= 2 / 515
= 2
Step3:
LCM(1, 140) = 140
GCD(1, 140) = ( 1 x 140 ) / 140
= 1 / 140
= 1
So, Greatest Common Divisor of 670, 138, 515, 140 is 1
