Given numbers are 621, 781, 501, 801
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(621, 781) = 485001
GCD(621, 781) = ( 621 x 781 ) / 485001
= 621 / 781
= 621
Step2:
LCM(1, 501) = 501
GCD(1, 501) = ( 1 x 501 ) / 501
= 1 / 501
= 1
Step3:
LCM(1, 801) = 801
GCD(1, 801) = ( 1 x 801 ) / 801
= 1 / 801
= 1
So, Greatest Common Divisor of 621, 781, 501, 801 is 1
