Given numbers are 870, 725, 248, 153
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(870, 725) = 4350
GCD(870, 725) = ( 870 x 725 ) / 4350
= 870 / 725
= 870
Step2:
LCM(145, 248) = 35960
GCD(145, 248) = ( 145 x 248 ) / 35960
= 145 / 248
= 145
Step3:
LCM(1, 153) = 153
GCD(1, 153) = ( 1 x 153 ) / 153
= 1 / 153
= 1
So, Greatest Common Divisor of 870, 725, 248, 153 is 1
