Given numbers are 649, 574, 417, 624
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 574) = 372526
GCD(649, 574) = ( 649 x 574 ) / 372526
= 649 / 574
= 649
Step2:
LCM(1, 417) = 417
GCD(1, 417) = ( 1 x 417 ) / 417
= 1 / 417
= 1
Step3:
LCM(1, 624) = 624
GCD(1, 624) = ( 1 x 624 ) / 624
= 1 / 624
= 1
So, Greatest Common Divisor of 649, 574, 417, 624 is 1
