Given numbers are 870, 687, 652, 975
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(870, 687) = 199230
GCD(870, 687) = ( 870 x 687 ) / 199230
= 870 / 687
= 870
Step2:
LCM(3, 652) = 1956
GCD(3, 652) = ( 3 x 652 ) / 1956
= 3 / 652
= 3
Step3:
LCM(1, 975) = 975
GCD(1, 975) = ( 1 x 975 ) / 975
= 1 / 975
= 1
So, Greatest Common Divisor of 870, 687, 652, 975 is 1
