Given numbers are 976, 958, 616, 645
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(976, 958) = 467504
GCD(976, 958) = ( 976 x 958 ) / 467504
= 976 / 958
= 976
Step2:
LCM(2, 616) = 616
GCD(2, 616) = ( 2 x 616 ) / 616
= 2 / 616
= 2
Step3:
LCM(2, 645) = 1290
GCD(2, 645) = ( 2 x 645 ) / 1290
= 2 / 645
= 2
So, Greatest Common Divisor of 976, 958, 616, 645 is 1
