Given numbers are 621, 771, 257, 370
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(621, 771) = 159597
GCD(621, 771) = ( 621 x 771 ) / 159597
= 621 / 771
= 621
Step2:
LCM(3, 257) = 771
GCD(3, 257) = ( 3 x 257 ) / 771
= 3 / 257
= 3
Step3:
LCM(1, 370) = 370
GCD(1, 370) = ( 1 x 370 ) / 370
= 1 / 370
= 1
So, Greatest Common Divisor of 621, 771, 257, 370 is 1
