Given numbers are 649, 977, 505, 813
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 977) = 634073
GCD(649, 977) = ( 649 x 977 ) / 634073
= 649 / 977
= 649
Step2:
LCM(1, 505) = 505
GCD(1, 505) = ( 1 x 505 ) / 505
= 1 / 505
= 1
Step3:
LCM(1, 813) = 813
GCD(1, 813) = ( 1 x 813 ) / 813
= 1 / 813
= 1
So, Greatest Common Divisor of 649, 977, 505, 813 is 1
