Given numbers are 145, 870, 523, 493
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(145, 870) = 870
GCD(145, 870) = ( 145 x 870 ) / 870
= 145 / 870
= 145
Step2:
LCM(145, 523) = 75835
GCD(145, 523) = ( 145 x 523 ) / 75835
= 145 / 523
= 145
Step3:
LCM(1, 493) = 493
GCD(1, 493) = ( 1 x 493 ) / 493
= 1 / 493
= 1
So, Greatest Common Divisor of 145, 870, 523, 493 is 1
