Given numbers are 690, 705, 892
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 705) = 32430
GCD(690, 705) = ( 690 x 705 ) / 32430
= 690 / 705
= 690
Step2:
LCM(15, 892) = 13380
GCD(15, 892) = ( 15 x 892 ) / 13380
= 15 / 892
= 15
So, Greatest Common Divisor of 690, 705, 892 is 1
