Given numbers are 870, 660, 383, 140
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(870, 660) = 19140
GCD(870, 660) = ( 870 x 660 ) / 19140
= 870 / 660
= 870
Step2:
LCM(30, 383) = 11490
GCD(30, 383) = ( 30 x 383 ) / 11490
= 30 / 383
= 30
Step3:
LCM(1, 140) = 140
GCD(1, 140) = ( 1 x 140 ) / 140
= 1 / 140
= 1
So, Greatest Common Divisor of 870, 660, 383, 140 is 1
