Given numbers are 802, 870, 372, 981
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(802, 870) = 348870
GCD(802, 870) = ( 802 x 870 ) / 348870
= 802 / 870
= 802
Step2:
LCM(2, 372) = 372
GCD(2, 372) = ( 2 x 372 ) / 372
= 2 / 372
= 2
Step3:
LCM(2, 981) = 1962
GCD(2, 981) = ( 2 x 981 ) / 1962
= 2 / 981
= 2
So, Greatest Common Divisor of 802, 870, 372, 981 is 1
