Given numbers are 857, 634, 523, 690
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(857, 634) = 543338
GCD(857, 634) = ( 857 x 634 ) / 543338
= 857 / 634
= 857
Step2:
LCM(1, 523) = 523
GCD(1, 523) = ( 1 x 523 ) / 523
= 1 / 523
= 1
Step3:
LCM(1, 690) = 690
GCD(1, 690) = ( 1 x 690 ) / 690
= 1 / 690
= 1
So, Greatest Common Divisor of 857, 634, 523, 690 is 1
