Given numbers are 651, 248, 355, 961
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(651, 248) = 5208
GCD(651, 248) = ( 651 x 248 ) / 5208
= 651 / 248
= 651
Step2:
LCM(31, 355) = 11005
GCD(31, 355) = ( 31 x 355 ) / 11005
= 31 / 355
= 31
Step3:
LCM(1, 961) = 961
GCD(1, 961) = ( 1 x 961 ) / 961
= 1 / 961
= 1
So, Greatest Common Divisor of 651, 248, 355, 961 is 1
