Given numbers are 776, 396, 690, 821
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(776, 396) = 76824
GCD(776, 396) = ( 776 x 396 ) / 76824
= 776 / 396
= 776
Step2:
LCM(4, 690) = 1380
GCD(4, 690) = ( 4 x 690 ) / 1380
= 4 / 690
= 4
Step3:
LCM(2, 821) = 1642
GCD(2, 821) = ( 2 x 821 ) / 1642
= 2 / 821
= 2
So, Greatest Common Divisor of 776, 396, 690, 821 is 1
