Given numbers are 621, 647, 581, 590
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(621, 647) = 401787
GCD(621, 647) = ( 621 x 647 ) / 401787
= 621 / 647
= 621
Step2:
LCM(1, 581) = 581
GCD(1, 581) = ( 1 x 581 ) / 581
= 1 / 581
= 1
Step3:
LCM(1, 590) = 590
GCD(1, 590) = ( 1 x 590 ) / 590
= 1 / 590
= 1
So, Greatest Common Divisor of 621, 647, 581, 590 is 1
