Given numbers are 129, 735, 445, 870
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(129, 735) = 31605
GCD(129, 735) = ( 129 x 735 ) / 31605
= 129 / 735
= 129
Step2:
LCM(3, 445) = 1335
GCD(3, 445) = ( 3 x 445 ) / 1335
= 3 / 445
= 3
Step3:
LCM(1, 870) = 870
GCD(1, 870) = ( 1 x 870 ) / 870
= 1 / 870
= 1
So, Greatest Common Divisor of 129, 735, 445, 870 is 1
