Given numbers are 861, 707, 869, 275
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 707) = 86961
GCD(861, 707) = ( 861 x 707 ) / 86961
= 861 / 707
= 861
Step2:
LCM(7, 869) = 6083
GCD(7, 869) = ( 7 x 869 ) / 6083
= 7 / 869
= 7
Step3:
LCM(1, 275) = 275
GCD(1, 275) = ( 1 x 275 ) / 275
= 1 / 275
= 1
So, Greatest Common Divisor of 861, 707, 869, 275 is 1
